Description

本発明は、フォグランプを取り付けるベゼル等の外装部品をバンパーカバー等の車体に取り付ける構造に関する。 The present invention relates to a structure for attaching an exterior component such as a bezel for attaching a fog lamp to a vehicle body such as a bumper cover.

従来、外装部品に爪部やクリップを備えておき、車体に設けられた孔部に上記爪部等を挿入すると共に孔部の開口縁に係合させることで、外装部品を車体に取り付けることがなされている。特許文献１は、メッキガーニッシュの爪部をバンパーカバーの穴部に挿入する構造を開示する。特許文献２は、サイドストーンガードに設けられたボックス部にクリップを取り付け、このクリップをボディの側部に設けられた穴部に挿入する構造を開示する。 Conventionally, the exterior parts are provided with claws and clips, and the exterior parts are attached to the vehicle body by inserting the claws and the like into the holes provided in the vehicle body and engaging with the opening edges of the holes. It has been done. Patent Document 1 discloses a structure in which a claw portion of a plating garnish is inserted into a hole portion of a bumper cover. Patent Document 2 discloses a structure in which a clip is attached to a box provided on a side stone guard, and the clip is inserted into a hole provided on a side of the body.

上述の爪部を外装部品の裏面に直接設けると、意匠面である外装部品の表面にヒケが生じて、外観を損なうことがある。そのため、特許文献１に記載されるように、爪部の根元側にブラケット部を設けることがある。ブラケット部や上述のクリップを取り付けるボックス部は、外装部品の裏面との間に所定の空間をつくる箱状（有底筒状）であり、開口部を有する。 If the above-described claw portion is provided directly on the back surface of the exterior component, sink marks may be generated on the surface of the exterior component, which is a design surface, and the appearance may be impaired. Therefore, as described in Patent Literature 1, a bracket portion may be provided on the base side of the claw portion. The box part to which the bracket part and the above-mentioned clip are attached has a box shape (bottomed cylindrical shape) that creates a predetermined space between the bracket part and the back surface of the exterior component, and has an opening.

車体における外装部品の取付箇所から、風流れに起因した異音の発生を低減することが望まれている。 It is desired to reduce the generation of abnormal noise due to the wind flow from the mounting location of the exterior component on the vehicle body.

上述のブラケット部は、外装部品の周縁に開口するように設けられることがある。ここで、外装部品の爪部と車体の孔部との機械的な嵌め合いでは、外装部品の周縁と車体における外装部品の取付箇所との間に不可避的な隙間が生じる。上記隙間があると、車両の走行時、走行風、特に風速が大きい走行風が上記隙間からブラケット部の開口部を経てブラケット部内に侵入することがある。上述の走行風の侵入によって、ブラケット部の内部空間を利用して、空間共鳴による異音が生じ得る。空間共鳴による異音の発生は、上述のクリップ用のボックス部についても同様である。 The above-mentioned bracket part may be provided so as to open to the peripheral edge of the exterior component. Here, in the mechanical fitting between the claw portion of the exterior component and the hole of the vehicle body, an unavoidable gap occurs between the peripheral edge of the exterior component and the mounting position of the exterior component on the vehicle body. If the gap is provided, a traveling wind, particularly a traveling wind having a high wind speed, may enter the bracket from the gap via the opening of the bracket when the vehicle travels. Due to the invasion of the traveling wind described above, abnormal noise due to spatial resonance may be generated using the internal space of the bracket portion. The generation of abnormal noise due to spatial resonance is the same for the above-described clip box.

例えば、特許文献２に記載されるようにボックス部の連結壁に貫通孔を設ければ、上述の隙間からボックス部内に入り込んだ風は、ボックス部内を滞留せず、通過できる。そのため、上述の空間共鳴による異音の発生を防止できる。しかし、この場合には、上記隙間から侵入した風が上記連結壁の貫通孔からボックス部内を経てボックス部の開口部に抜ける、又はその逆に抜けることで、風切り異音を生じることが考えられる。 For example, if a through-hole is provided in the connection wall of the box portion as described in Patent Literature 2, the wind that has entered the box portion from the above-described gap can pass without remaining in the box portion. Therefore, generation of abnormal noise due to the above-described spatial resonance can be prevented. However, in this case, it is conceivable that wind entering through the gap passes through the through-hole of the connecting wall and passes through the inside of the box to the opening of the box, or vice versa, thereby generating wind noise. .

又は、例えば、外装部品の周縁に沿って、上述の隙間をシール材等で埋めれば、上記隙間からブラケット部内等に上述の走行風が入り込むことを防止できる。しかし、この場合には、シール材の充填作業が必要であり、製造工程数の増加を招く。また、シール材等の部品点数の増加によるコストアップを招く。 Alternatively, for example, if the above-mentioned gap is filled with a sealing material or the like along the peripheral edge of the exterior component, the above-described traveling wind can be prevented from entering the inside of the bracket portion or the like from the above-mentioned gap. However, in this case, a filling operation of the sealing material is necessary, which causes an increase in the number of manufacturing steps. In addition, the cost is increased due to an increase in the number of parts such as a sealing material.

本発明は上記事情に鑑みてなされたものであり、その目的の一つは、単純な形状でありながら、異音の発生を低減できる外装部品の取付構造を提供することにある。 The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a mounting structure for an exterior component which has a simple shape and can reduce generation of abnormal noise.

本発明の一態様に係る外装部品の取付構造は、
外装部品の裏面から突出する取付片が車体に設けられた孔部に差し込まれた外装部品の取付構造であって、
前記取付片は、
前記孔部の開口縁に係合する先端部と、
前記取付片の根元側に位置し、前記先端部を支持する台座部とを備え、
前記台座部は、
前記外装部品の裏面との間に所定の空間を形成すると共に、前記外装部品の周縁に開口する門型片を備え、
前記車体は、
前記車体の表面における前記孔部の近傍から外方に突出して、前記台座部の開口を塞ぐリブを備える。 The mounting structure of the exterior component according to one embodiment of the present invention,
A mounting structure of the exterior component in which a mounting piece protruding from the back surface of the exterior component is inserted into a hole provided in the vehicle body,
The mounting piece,
A tip portion that engages with an opening edge of the hole,
A pedestal portion that is located on the base side of the mounting piece and supports the distal end portion,
The pedestal,
Forming a predetermined space between the back surface of the exterior component, and comprises a gate-shaped piece that opens to the periphery of the exterior component,
The car body is
A rib protruding outward from the vicinity of the hole on the surface of the vehicle body to close an opening of the pedestal is provided.

上記の外装部品の取付構造は、以下に説明するように異音の発生を低減できる。
上記の外装部品の取付構造では、外装部品の台座部が外装部品の周縁に開口するものの、台座部の開口は車体のリブによって塞がれる。このリブによって、車両の走行時、走行風、特に風速が大きい走行風が、外装部品の周縁と車体における外装部品の取付箇所との間に生じる不可避的な隙間から台座部内に侵入することを防止できる。そのため、台座部内への走行風の侵入に起因する空間共鳴の発生を防止できる。その結果、上記空間共鳴による異音の発生を低減できる。 The above mounting structure of the exterior component can reduce occurrence of abnormal noise as described below.
In the above mounting structure of the exterior component, the pedestal portion of the exterior component opens at the periphery of the exterior component, but the opening of the pedestal portion is closed by the rib of the vehicle body. These ribs prevent the traveling wind, especially the traveling wind with a high wind speed, from entering the pedestal portion through an unavoidable gap generated between the periphery of the exterior component and the mounting position of the exterior component on the vehicle body when the vehicle travels. it can. Therefore, it is possible to prevent the occurrence of spatial resonance due to the intrusion of the traveling wind into the pedestal portion. As a result, generation of abnormal noise due to the spatial resonance can be reduced.

更に、上記の外装部品の取付構造は、車体にリブを設けるという簡単な構成である。リブは、車体の成形時に同時に成形できる。そのため、リブの増設に伴う製造工程数の増加を実質的に招かない。これらの点から、上記の外装部品の取付構造は、製造性にも優れ、製造コストも低減できる。 Further, the mounting structure of the exterior component has a simple configuration in which a rib is provided on the vehicle body. The ribs can be formed at the same time when the body is formed. For this reason, the increase in the number of manufacturing steps associated with the additional ribs does not substantially occur. From these points, the mounting structure of the exterior component described above is excellent in manufacturability and can reduce the manufacturing cost.

〈概要〉
実施形態１の外装部品の取付構造１（図４）は、自動車等の車両において車体３に外装部品２を装着することに利用される。ここでは、外装部品２としてフォグランプを取り付けるベゼル、車体３としてバンパーカバーを例示する。外装部品２は、裏面２ｂから突出する取付片２１，２７を備える（図１，図２）。車体３は、取付片２１，２７が挿入される孔部３２を備える（図１，図３）。外装部品の取付構造１は、外装部品２の取付片２１が車体３の孔部３２に差し込まれることで構築される（図４）。 <Overview>
The exterior component mounting structure 1 (FIG. 4) of the first embodiment is used to mount the exterior component 2 to the vehicle body 3 in a vehicle such as an automobile. Here, a bezel to which a fog lamp is attached as the exterior component 2 and a bumper cover as the vehicle body 3 are exemplified. The exterior component 2 includes mounting pieces 21 and 27 protruding from the back surface 2b (FIGS. 1 and 2). The vehicle body 3 includes a hole 32 into which the mounting pieces 21 and 27 are inserted (FIGS. 1 and 3). The external component mounting structure 1 is constructed by inserting the mounting piece 21 of the external component 2 into the hole 32 of the vehicle body 3 (FIG. 4).

なお、図１は、実施形態１の外装部品の取付構造を構築する前において、車体３に外装部品２を取り付ける状態を説明する分解斜視図である。図１では、車体３における外装部品２の取付箇所３１及びその近傍領域を部分的に示す。図１の紙面左右方向は、概ね車幅方向に相当し、紙面上下方向は車両上下方向に相当する。

FIG. 1 partially shows a mounting portion 31 of the exterior component 2 in the vehicle body 3 and a region in the vicinity thereof. The left-right direction in FIG. 1 substantially corresponds to the vehicle width direction, and the vertical direction in FIG. 1 corresponds to the vehicle vertical direction.

FIG. 3 is a plan view and a perspective view partially showing a hole 32 and a region near the hole 32 in a mounting portion 31 of the exterior component 2 in the vehicle body 3.
FIG. 4 illustrates a state in which the exterior component 2 is attached to the vehicle body 3 (hereinafter, referred to as an exterior component attachment state), that is, a state in which the exterior component attachment structure 1 of the first embodiment is constructed. It is sectional drawing cut | disconnected by a parallel plane. FIG. 4 partially shows the mounting piece 21 of the exterior component 2 and its vicinity, and the vehicle body 3. 4 corresponds to the vehicle width direction.

図２に示すように外装部品２の取付片２１は、外装部品２の裏面２ｂとの間に所定の空間を形成する門型状の台座部２３を備える。本例の台座部２３は、門の一方が閉じた箱状（有底筒状）であり、門の他方は外装部品２の周縁（ここではフランジ部２０ｆ）に開口する。特に、実施形態１の外装部品の取付構造１では、車体３が、台座部２３の開口２３５を塞ぐリブ３３を備える（図３，図４）。リブ３３によって台座部２３の開口２３５を塞ぐことで台座部２３内への走行風の侵入を防止する。このようなリブ３３は、台座部２３内への走行風の侵入に起因する空間共鳴の発生を防止することに寄与する。 As shown in FIG. 2, the mounting piece 21 of the exterior component 2 includes a gate-shaped pedestal portion 23 that forms a predetermined space between the attachment piece 21 and the back surface 2 b of the exterior component 2. The pedestal portion 23 of the present example is a box-like (bottomed cylindrical shape) in which one of the gates is closed, and the other of the gate is open at the periphery of the exterior component 2 (here, the flange portion 20f). In particular, in the exterior component mounting structure 1 of the first embodiment, the vehicle body 3 includes the rib 33 that closes the opening 235 of the pedestal 23 (FIGS. 3 and 4). By closing the opening 235 of the pedestal portion 23 with the rib 33, the traveling wind can be prevented from entering the pedestal portion 23. Such ribs 33 contribute to preventing the occurrence of spatial resonance due to the intrusion of the traveling wind into the pedestal portion 23.

以下、まず、外装部品２が装着される車体３の概要を説明する。次に、外装部品２を詳細に説明する。その後に、車体３のリブ３３及びその周辺構成を詳細に説明する。 Hereinafter, first, an outline of the vehicle body 3 to which the exterior component 2 is mounted will be described. Next, the exterior component 2 will be described in detail. After that, the rib 33 of the vehicle body 3 and its peripheral configuration will be described in detail.

〈車体（バンパーカバー）の概要〉
主に図１を参照して、車体３の概要を説明する。
本例のバンパーカバーは、自動車等の車両において、前方かつ下方に、車幅方向に沿って設けられるフロントバンパーカバーである。フロントバンパーとは、自動車等の車両の前方かつ下方に設けられる衝撃吸収装置である。代表的には、フロントバンパーは、車幅方向に沿って配置されるリインフォース（図示せず）と、リインフォースの前面に配置されるアブソーバ（図示せず）と、リインフォース及びアブソーバを覆うバンパーカバーとを備える。フロントバンパーカバーは、車両の走行時、その前面から走行風を受ける。 <Outline of body (bumper cover)>
An outline of the vehicle body 3 will be described mainly with reference to FIG.
The bumper cover of this example is a front bumper cover provided along the vehicle width direction forward and downward in a vehicle such as an automobile. The front bumper is an impact absorbing device provided in front of and below a vehicle such as an automobile. Typically, the front bumper includes a reinforce (not shown) arranged along the vehicle width direction, an absorber (not shown) arranged in front of the reinforce, and a bumper cover covering the reinforce and the absorber. . The front bumper cover receives traveling wind from the front when the vehicle travels.

本例のバンパーカバーは、本体３０と、グリル３ｇと、外装部品２の取付箇所３１とを備える。図１では、バンパーカバーのうち、車幅方向の右側領域のみを部分的に示す。本例の本体３０は、車幅方向に延びるように設けられる樹脂成形体である。グリル３ｇは、車内外の通気のための開口３ａを備える。本例のグリル３ｇは、本体３０とは独立した部品である。そのため、本体３０は、その車幅方向の中央部にグリル３ｇの取付箇所（図示せず）を備える。グリル３ｇは、上記取付箇所に装着される。 The bumper cover of this example includes a main body 30, a grill 3g, and a mounting portion 31 for the exterior component 2. FIG. 1 shows only a part of the right side of the bumper cover in the vehicle width direction. The main body 30 of this example is a resin molded body provided to extend in the vehicle width direction. The grill 3g has an opening 3a for ventilation inside and outside the vehicle. The grill 3g of this example is a component independent of the main body 30. Therefore, the main body 30 is provided with a mounting portion (not shown) for the grill 3g at the center in the vehicle width direction. The grill 3g is mounted on the mounting location.

本例の外装部品２の取付箇所３１は、本体３０における車幅方向の各端部に設けられる。取付箇所３１は、本体３０の表面３ｆにおいて、車両前方から車両後方に向かうように局所的に凹んだ箇所である。この凹みに沿って、取付箇所３１に外装部品２が取り付けられる。 The attachment portions 31 of the exterior component 2 of this example are provided at each end of the main body 30 in the vehicle width direction. The attachment portion 31 is a locally recessed portion on the surface 3f of the main body 30 from the front of the vehicle toward the rear of the vehicle. The exterior component 2 is attached to the attachment location 31 along the recess.

本例では、取付箇所３１の中央部にフォグランプ４（図４）が配置されるランプ用の貫通孔３ｈが設けられている。また、取付箇所３１の周縁近くには、取付箇所３１の周方向に離間して複数の凹部３ｒが設けられている。図１では、５個の凹部３ｒを備える場合を例示する。各凹部３ｒは、外装部品２の取付片２１，２７が嵌め込まれる箇所である（図４も参照）。各凹部３ｒの底部に、底部を貫通する孔部３２が設けられている（同）。車幅方向の外側に位置する凹部３ｒでは、孔部３２の近くにリブ３３が設けられている。リブ３３の詳細は後述する。 In the present example, a through hole 3 h for a lamp in which the fog lamp 4 (FIG. 4) is arranged is provided at the center of the mounting portion 31. Further, a plurality of recesses 3r are provided near the periphery of the attachment point 31 and are spaced apart in the circumferential direction of the attachment point 31. FIG. 1 illustrates a case where five concave portions 3r are provided. Each recess 3r is a place where the mounting pieces 21, 27 of the exterior component 2 are fitted (see also FIG. 4). At the bottom of each recess 3r, a hole 32 penetrating the bottom is provided (same as above). A rib 33 is provided near the hole 32 in the recess 3 r located outside in the vehicle width direction. The details of the rib 33 will be described later.

〈外装部品〉
主に図２を参照して、外装部品２を説明する。
外装部品２は、本体２０と、本体２０の裏面２ｂから突出する複数の取付片２１，２７とを備える。更に、本例の外装部品２は、外装部品２の周縁から立設されるフランジ部２０ｆを備え、取付片２１の台座部２３はフランジ部２０ｆに開口する。本例の外装部品２は、本体２０、取付片２１，２７、及びフランジ部２０ｆが一体に成形された樹脂成形体である。本例の外装部品２であるフォグランプを取り付けるベゼルは、フロントバンパーカバーに装着されると、車両の走行時、その前面から側面に流れるように走行風を受ける。 <Exterior parts>
The exterior component 2 will be described mainly with reference to FIG.
The exterior component 2 includes a main body 20 and a plurality of mounting pieces 21 and 27 protruding from the back surface 2b of the main body 20. Furthermore, the exterior component 2 of the present example includes a flange portion 20f that stands upright from the periphery of the exterior component 2, and the pedestal portion 23 of the mounting piece 21 opens to the flange portion 20f. The exterior component 2 of the present embodiment is a resin molded body in which the main body 20, the mounting pieces 21, 27, and the flange portion 20f are integrally formed. The bezel to which the fog lamp, which is the exterior component 2 of the present embodiment, is attached to the front bumper cover receives a traveling wind from the front to the side when the vehicle travels.

《本体》
本例の本体２０は、所定の形状（ここでは三角形状）を有する板状材である（図１も参照）。本例では、本体２０の中央部にフォグランプ４が配置されるランプ用の貫通孔２ｈを備える（同）。貫通孔２ｈは、表面２ｆ（図１，図４）から裏面２ｂを貫通する。本体２０の表面２ｆは、意匠面として利用される。本体２０の裏面２ｂは、車体３の表面３ｆのうち、取付箇所３１を覆うように配置される。《Body》
The main body 20 of the present example is a plate-shaped material having a predetermined shape (here, a triangular shape) (see also FIG. 1). In the present example, a lamp through-hole 2h in which the fog lamp 4 is arranged is provided at the center of the main body 20 (same as above). The through hole 2h penetrates from the front surface 2f (FIGS. 1 and 4) to the back surface 2b. The surface 2f of the main body 20 is used as a design surface. The back surface 2b of the main body 20 is disposed so as to cover the attachment portion 31 of the front surface 3f of the vehicle body 3.

フランジ部２０ｆは、板状の本体２０の周縁に沿って設けられている。フランジ部２０ｆは、裏面２ｂから車両後方に向かって立設され、本体２０の周縁に沿った概ね環状体である。環状のフランジ部２０ｆを有することで、外装部品２の強度を高められる。また、フランジ部２０ｆを有することで、外装部品２において、車体３の外装部品２の取付箇所３１との合わせ部分から外装部品２のエッジがみえず、見栄えがよい。更に、フランジ部２０ｆを有することで、本体２０の周縁に触れても安全である。但し、フランジ部２０ｆは、完全な環状体ではなく、フランジ部２０ｆの周方向の一部は切り欠かれている。フランジ部２０ｆの切欠箇所は、取付片２１の台座部２３の開口２３５を形成する。なお、フランジ部２０ｆの切欠箇所は、取付片２１の台座部２３を有底筒状に形成するための金型（入れ子型）を抜き取るために形成される。 The flange portion 20f is provided along the periphery of the plate-shaped main body 20. The flange portion 20 f is erected from the rear surface 2 b toward the rear of the vehicle, and is a substantially annular body along the periphery of the main body 20. By having the annular flange portion 20f, the strength of the exterior component 2 can be increased. Moreover, by having the flange portion 20f, in the exterior component 2, the edge of the exterior component 2 is not seen from the portion where the exterior component 2 of the vehicle body 3 is fitted with the attachment portion 31, and the appearance is good. Further, by having the flange portion 20f, it is safe to touch the peripheral edge of the main body 20. However, the flange portion 20f is not a complete annular body, and a part of the flange portion 20f in the circumferential direction is cut off. The cutout portion of the flange portion 20f forms an opening 235 of the pedestal portion 23 of the mounting piece 21. The cutout portion of the flange portion 20f is formed for extracting a mold (nested mold) for forming the pedestal portion 23 of the mounting piece 21 into a bottomed cylindrical shape.

《取付片》
取付片２１は、先端部２２と、台座部２３とを備える。先端部２２は、車体３の孔部３２の開口縁に係合する（図４も参照）。台座部２３は、取付片２１の根元側に位置し、先端部２２を支持する。《Mounting piece》
The mounting piece 21 includes a tip portion 22 and a pedestal portion 23. The tip portion 22 is engaged with the opening edge of the hole 32 of the vehicle body 3 (see also FIG. 4). The pedestal 23 is located on the base side of the mounting piece 21 and supports the tip 22.

本例の先端部２２は、平板状であり、爪部２２０と、スリット２２１と、基部２２２とを備える。詳しくは、平板状の基部２２２の中央部に、基部２２２の表裏に貫通するＵ字状のスリット２２１が設けられている。スリット２２１によって基部２２２から舌片が形成される。舌片は、舌片における挿入方向の先端側の領域が基部２２２に連結されることで、弾性変形可能である。この舌片が爪部２２０に相当する。 The distal end portion 22 of the present example has a flat plate shape and includes a claw portion 220, a slit 221, and a base portion 222. More specifically, a U-shaped slit 221 penetrating the front and back of the base 222 is provided at the center of the flat base 222. A tongue piece is formed from the base 222 by the slit 221. The tongue piece is elastically deformable by connecting a region on the tip end side in the insertion direction of the tongue piece to the base 222. This tongue piece corresponds to the claw portion 220.

爪部２２０は、車体３の孔部３２の開口縁に直接係合する部分である。本例の爪部２２０は、孔部３２の開口縁に引っ掛かる突起を備える（図４も参照）。この突起は、爪部２２０における挿入方向の後端側の領域に設けられ、外装部品２の外方に向かって突出する。 The claw 220 is a portion that directly engages with the opening edge of the hole 32 of the vehicle body 3. The claw 220 of the present example includes a projection that is hooked on the opening edge of the hole 32 (see also FIG. 4). The projection is provided in a region on the rear end side in the insertion direction of the claw portion 220, and projects outward of the exterior component 2.

本例の基部２２２は、その挿入方向の先端側の領域が三角形状である。そのため、取付片２１を車体３の孔部３２に挿入し易い。また、本例の基部２２２は、その挿入方向の後端側の領域、つまり台座部２３との連結箇所近くの領域の表裏面、及び側面にそれぞれ、補強リブを備える。補強リブを備えることで、先端部２２が比較的薄い板材であっても強度に優れる。そのため、先端部２２全体を厚板とする場合に比較して、所定の強度を有しつつ、軽量化、材料の削減が可能である。 The base 222 of the present example has a triangular shape in the region on the distal end side in the insertion direction. Therefore, it is easy to insert the mounting piece 21 into the hole 32 of the vehicle body 3. Further, the base 222 of the present example is provided with reinforcing ribs on the front and back surfaces and side surfaces of the region on the rear end side in the insertion direction, that is, the region near the connection point with the pedestal portion 23. By providing the reinforcing ribs, the strength is excellent even when the distal end portion 22 is a relatively thin plate material. For this reason, it is possible to reduce the weight and reduce the material while maintaining the predetermined strength, as compared with the case where the entire distal end portion 22 is made of a thick plate.

台座部２３は、外装部品２の裏面２ｂとの間に所定の空間を形成すると共に、外装部品２の周縁（ここではフランジ部２０ｆ）に開口する門型片を有する。本例の台座部２３は、外装部品２の裏面２ｂから立設される一対の側壁部２３０、及び両側壁部２３０を繋ぐ連結壁部２３１（図４）と、側壁部２３０の周縁及び連結壁部２３１の周縁に接続され、外装部品２の裏面２ｂに対向して配置される天井部２３２とを備える。 The pedestal portion 23 forms a predetermined space between itself and the back surface 2b of the exterior component 2 and has a gate-shaped piece that opens at the periphery of the exterior component 2 (here, the flange portion 20f). The pedestal portion 23 of the present example includes a pair of side wall portions 230 erected from the back surface 2b of the exterior component 2, a connecting wall portion 231 (FIG. 4) connecting the both side wall portions 230, and a peripheral edge and a connecting wall of the side wall portion 230. A ceiling portion 232 connected to the peripheral edge of the portion 231 and arranged to face the back surface 2b of the exterior component 2.

両側壁部２３０と天井部２３２とで門を形成する。上記門の一方の開口部は、フランジ部２０ｆの切欠箇所に配置される。上記門の他方の開口部は、連結壁部２３１によって塞がれる。従って、本例の台座部２３は、一方が開口し、他方が開口しない門型片、いわば有底筒状である。台座部２３の開口２３５は、主として、両側壁部２３０の周縁と、天井部２３２の周縁と、外装部品２の裏面２ｂの周縁とによって形成される。 A gate is formed by the side walls 230 and the ceiling 232. One opening of the gate is arranged at a cutout portion of the flange portion 20f. The other opening of the gate is closed by the connecting wall 231. Therefore, the pedestal portion 23 of this example is a gate-shaped piece that is open on one side and does not open on the other side, that is, a bottomed cylindrical shape. The opening 235 of the pedestal portion 23 is mainly formed by the peripheral edges of the side wall portions 230, the peripheral edge of the ceiling portion 232, and the peripheral edge of the back surface 2b of the exterior component 2.

連結壁部２３１を備えて有底筒状である台座部２３は、連結壁部２３１を備えていない場合に比較して、強度に優れる。但し、有底筒状の台座部２３では、走行風が開口２３５から台座部２３内に侵入すると、台座部２３内に滞留し得る。 The pedestal portion 23 having the connecting wall portion 231 and having a bottomed cylindrical shape is superior in strength as compared with the case where the connecting wall portion 231 is not provided. However, in the bottomed cylindrical pedestal portion 23, if the traveling wind enters the pedestal portion 23 through the opening 235, it may stay in the pedestal portion 23.

その他、本例の外装部品２は取付片２７を備える。取付片２７は、上述の取付片２１と同様に先端部２２と台座部２８とを備える。但し、取付片２７の台座部２８は、外装部品２の周縁（ここではフランジ部２０ｆ）に開口しない門型片である。このように外装部品２は、台座部２８が外装部品２の周縁に開口しない取付片２７を備えてもよい。 In addition, the exterior component 2 of this example includes a mounting piece 27. The mounting piece 27 includes a distal end portion 22 and a pedestal portion 28, similarly to the mounting piece 21 described above. However, the pedestal portion 28 of the mounting piece 27 is a gate-shaped piece that does not open to the periphery of the exterior component 2 (here, the flange portion 20f). As described above, the exterior component 2 may include the mounting piece 27 in which the pedestal portion 28 does not open to the peripheral edge of the exterior component 2.

台座部２８は、台座部２３と同様に、一対の側壁部２３０と、連結壁部と、天井部２３２とを備える。台座部２８では、両側壁部２３０がフランジ部２０ｆに対向するように設けられる。両側壁部２３０と天井部２３２とで形成する門の一方が外装部品２の内部空間に開口し、上記門の他方が連結壁部によって塞がれる。外装部品の装着状態では、上述の台座部２８の開口は、車体３の凹部３ｒを形成する内側壁に塞がれる（図示せず）。 The pedestal portion 28 includes a pair of side wall portions 230, a connecting wall portion, and a ceiling portion 232, similarly to the pedestal portion 23. In the pedestal portion 28, both side wall portions 230 are provided so as to face the flange portion 20f. One of the gates formed by the side wall portions 230 and the ceiling portion 232 opens into the internal space of the exterior component 2, and the other of the gates is closed by the connecting wall portion. In the mounted state of the exterior component, the opening of the pedestal portion 28 is closed by an inner wall forming the concave portion 3r of the vehicle body 3 (not shown).

本例の外装部品２では、外装部品２の車幅方向の外側に配置される三つの取付片を、外装部品２の周縁に開口する台座部２３を備える取付片２１とする。上記車幅方向の内側に配置される二つの取付片を、外装部品２の周縁に開口しない台座部２３を備える取付片２７とする。取付片２１については、外装部品２の周縁に沿った風の流れに対して、台座部２３が開口するといえる。しかし、上述のように車体３のリブ３３によって台座部２３内への風の流入を防止できる。また、上述のフランジ部２０ｆによっても、台座部２３内への風の流入を低減できる。その結果、台座部２３は、上記風の流れに起因する空間共鳴の発生を低減し易い。取付片２７については、外装部品２の周縁に沿った風の流れに対して、台座部２７が開口していないといえる。そのため、取付片２７は、上記風の流れに起因する空間共鳴が実質的に発生しない。この配置は例示であり、適宜変更できる。 In the exterior component 2 of the present example, the three attachment pieces disposed outside the exterior component 2 in the vehicle width direction are the attachment pieces 21 having the pedestal portions 23 that open to the peripheral edge of the exterior component 2. The two mounting pieces arranged on the inner side in the vehicle width direction are referred to as mounting pieces 27 having a pedestal portion 23 that does not open on the periphery of the exterior component 2. Regarding the mounting piece 21, the pedestal portion 23 can be said to be opened with respect to the flow of wind along the peripheral edge of the exterior component 2. However, as described above, the inflow of wind into the pedestal portion 23 can be prevented by the rib 33 of the vehicle body 3. Further, the inflow of wind into the pedestal portion 23 can be reduced by the above-described flange portion 20f. As a result, the pedestal portion 23 can easily reduce the occurrence of spatial resonance caused by the flow of the wind. Regarding the attachment piece 27, it can be said that the pedestal portion 27 is not open to the flow of wind along the peripheral edge of the exterior component 2. Therefore, the mounting piece 27 does not substantially generate spatial resonance due to the flow of the wind. This arrangement is an example and can be changed as appropriate.

〈リブ及びその周辺構成〉
主に図３を参照して、リブ３３及びその周辺構成を説明する。
車体３は、上述のように外装部品２の取付箇所３１に、取付片２１，２７がそれぞれ嵌め込まれる凹部３ｒを備える。各凹部３ｒの形状、大きさは、各取付片２１，２７の台座部２３の形状、大きさに応じて設けられる。図３（Ａ）に示すように各凹部３ｒの底部には、上述のように孔部３２が設けられる。外装部品の装着状態では、各孔部３２に、各取付片２１，２７の先端部２２が挿入される。各凹部３ｒを形成する内壁部は、各取付片２１の台座部２３の側壁部２３０及び連結壁部２３１、各取付片２７の側壁部２３０及び上述の開口部を覆う。 <Rib and its surroundings>
The rib 33 and its peripheral configuration will be described mainly with reference to FIG.
The vehicle body 3 is provided with the concave portion 3r in which the mounting pieces 21 and 27 are fitted into the mounting location 31 of the exterior component 2 as described above. The shape and size of each recess 3r are provided according to the shape and size of the pedestal portion 23 of each of the mounting pieces 21 and 27. As shown in FIG. 3A, the hole 32 is provided at the bottom of each recess 3r as described above. In the mounted state of the exterior component, the distal end portion 22 of each of the mounting pieces 21 and 27 is inserted into each of the holes 32. The inner wall portion forming each recess 3r covers the side wall portion 230 and the connecting wall portion 231 of the pedestal portion 23 of each mounting piece 21, the side wall portion 230 of each mounting piece 27, and the above-described opening.

特に、取付片２１は、外装部品２の周縁に開口する台座部２３を備える。そのため、この取付片２１が配置される凹部３ｒには、車体３の表面３ｆにおいて孔部３２の近傍から外方に突出して、台座部２３の開口２３５を塞ぐリブ３３を備える。 In particular, the mounting piece 21 includes a pedestal portion 23 that opens to the periphery of the exterior component 2. Therefore, the concave portion 3 r in which the mounting piece 21 is disposed has a rib 33 protruding outward from the vicinity of the hole 32 on the surface 3 f of the vehicle body 3 and closing the opening 235 of the pedestal portion 23.

本例のリブ３３は、図３（Ｂ）に示すように凹部３ｒを形成する内壁部の一部から延設される。リブ３３の形状、大きさは、外装部品の装着状態において、取付片２１の開口２３５を適切に塞ぐことができる範囲で適宜調整できる。本例では、長方形状の開口２３５に対応して（図２参照）、リブ３３を長方形状の平板材とする。このようなリブ３３は単純な形状であり、成形し易い。 As shown in FIG. 3B, the rib 33 of the present example extends from a part of the inner wall forming the recess 3r. The shape and size of the rib 33 can be appropriately adjusted within a range in which the opening 235 of the attachment piece 21 can be properly closed in a state where the exterior component is mounted. In this example, the rib 33 is a rectangular flat plate corresponding to the rectangular opening 235 (see FIG. 2). Such a rib 33 has a simple shape and is easy to mold.

〈構成材料〉
外装部品２及び車体３を構成する樹脂は、公知のものを利用できる。また、外装部品２及び車体３は、射出成形といった公知の成形法によって製造できる。 <Constituent materials>
Known resins can be used for the resin constituting the exterior component 2 and the vehicle body 3. The exterior component 2 and the vehicle body 3 can be manufactured by a known molding method such as injection molding.

〈その他〉
外装部品２の取付片２１，２７の形成位置、個数、大きさ、形状等は適宜変更できる。車体３の外装部品２の取付箇所３１における凹部３ｒ、孔部３２の形成位置、個数、大きさ、形状等は、外装部品２の取付片２１，２７の形成位置、個数、大きさ、形状等に応じて調整するとよい。リブ３３の形成位置、個数、大きさ、形状等は、外装部品２の取付片２１の形成位置、個数、台座部２３の開口２３５の大きさ、形状等に応じて調整するとよい。 <Others>
The formation position, number, size, shape, and the like of the mounting pieces 21 and 27 of the exterior component 2 can be appropriately changed. The formation position, number, size, shape, and the like of the concave portion 3r and the hole 32 in the attachment portion 31 of the exterior component 2 of the vehicle body 3 are the formation position, the number, the size, the shape, and the like of the mounting pieces 21, 27 of the exterior component 2. It may be adjusted according to. The formation position, the number, the size, the shape, and the like of the ribs 33 may be adjusted according to the formation position, the number, and the size, the shape, and the like of the mounting pieces 21 of the exterior component 2 and the opening 235 of the pedestal portion 23.

［作用・効果］
実施形態１の外装部品の取付構造１は、図２に示すように外装部品２の台座部２３が外装部品２の周縁（ここではフランジ部２０ｆ）に開口する取付片２１を備える。しかし、外装部品の取付構造１では、車体３がリブ３３を備えており、リブ３３が取付片２１の台座部２３の開口２３５を塞ぐ。そのため、図４に示すように、車両の走行時、走行風、特に風速が大きい走行風が、外装部品２の周縁と車体３における外装部品２の取付箇所３１との間に生じる不可避的な隙間から、取付片２１の台座部２３内に侵入しようとしても、リブ３３によって台座部２３内への走行風の侵入を阻止できる。なお、図４の細線矢印は走行風の流れを模式的に示す。 [Action / Effect]
As shown in FIG. 2, the mounting structure 1 of the exterior component according to the first embodiment includes a mounting piece 21 in which the pedestal portion 23 of the exterior component 2 is opened on the peripheral edge of the exterior component 2 (here, the flange portion 20f). However, in the exterior component mounting structure 1, the vehicle body 3 includes the rib 33, and the rib 33 closes the opening 235 of the pedestal portion 23 of the mounting piece 21. Therefore, as shown in FIG. 4, when the vehicle travels, an unavoidable gap is generated between the peripheral edge of the exterior component 2 and the mounting portion 31 of the exterior component 2 in the vehicle body 3 when the traveling wind, particularly the traveling wind having a high wind speed, is generated. Therefore, even if it is attempted to enter the pedestal portion 23 of the mounting piece 21, the rib 33 can prevent the traveling wind from entering the pedestal portion 23. The thin arrows in FIG. 4 schematically show the flow of the traveling wind.

従って、実施形態１の外装部品の取付構造１は、車両の走行時、上述の走行風が取付片２１の台座部２３内に侵入することに起因する空間共鳴の発生を防止できる。このような外装部品の取付構造１は、上記空間共鳴による異音の発生を低減できる。 Therefore, the exterior component mounting structure 1 of the first embodiment can prevent the occurrence of spatial resonance caused by the above-described traveling wind entering the pedestal portion 23 of the mounting piece 21 when the vehicle travels. The mounting structure 1 of the exterior component can reduce the generation of abnormal noise due to the spatial resonance.

本例の取付片２１に備えられる台座部２３は、連結壁部２３１を有する有底筒状である。そのため、上述の隙間から侵入した風が外装部品２と車体３の取付箇所３１との間の空間に侵入し、再び上記隙間から抜けようとしても、リブ３３によってこの通り抜けを阻止することが期待できる。このような外装部品の取付構造１は、上述の走行風の通り抜けに起因する風切り異音の発生も低減できると期待される。 The pedestal portion 23 provided on the mounting piece 21 of this example is a bottomed cylindrical shape having a connecting wall portion 231. Therefore, even if the wind that has entered through the above-described gap enters the space between the exterior component 2 and the mounting portion 31 of the vehicle body 3 and attempts to escape through the above-described gap again, it can be expected that the rib 33 prevents the passage. . Such an exterior component mounting structure 1 is expected to be able to reduce the occurrence of wind noise caused by the passage of the traveling wind.

更に、本例の取付片２１は連結壁部２３１を有することで、フォグランプ４からの光が上述の隙間から漏れ出ることも防止できる。そのため、見栄えが良く、商品価値を高められる。 Further, since the mounting piece 21 of the present example has the connecting wall portion 231, it is possible to prevent the light from the fog lamp 4 from leaking from the above-described gap. Therefore, the appearance is good and the commercial value can be enhanced.

更に、本例の外装部品の取付構造１では、フロントバンパーカバーが受けた走行風は、図４の細線矢印に示すように、主としてフロントバンパーカバーの表面に沿って流れる。特に、上記走行風は、バンパーコーナー部においても車両表面から剥離し難く、車両表面に沿って流れる。この点から、空力特性（Ｃｄ値）の向上が期待される。 Furthermore, in the exterior component mounting structure 1 of the present example, the traveling wind received by the front bumper cover flows mainly along the surface of the front bumper cover as shown by the thin line arrow in FIG. In particular, the traveling wind hardly separates from the vehicle surface even at the bumper corners, and flows along the vehicle surface. From this point, improvement in aerodynamic characteristics (Cd value) is expected.

また、実施形態１の外装部品の取付構造１は、車体３にリブ３３を設けるという簡単な構成でありながら、上述のように異音の発生を低減できる。本例のように車体３が樹脂成形体であれば、リブ３３は、車体３の成形時に同時に成形できる。本例のリブ３３は、上述のように長方形の平板状という単純な形状であることからも、成形性に優れる。これらのことから、リブ３３の増設に伴う製造工程数の増加を招かず、製造性にも優れる。また、上述の隙間をシール材で埋める必要も無いことからも、製造性に優れる。更に、製造コストも低減できる。 In addition, the exterior component mounting structure 1 according to the first embodiment has a simple configuration in which the ribs 33 are provided on the vehicle body 3, but can reduce the generation of abnormal noise as described above. When the vehicle body 3 is a resin molded body as in this example, the ribs 33 can be formed at the same time when the vehicle body 3 is formed. Since the rib 33 of this example has a simple shape of a rectangular flat plate as described above, it is excellent in moldability. For these reasons, the number of manufacturing steps is not increased due to the additional ribs 33, and the manufacturability is excellent. In addition, since there is no need to fill the gap with a sealing material, the productivity is excellent. Further, manufacturing costs can be reduced.

［変形例］
上述した実施形態１の外装部品の取付構造１に対して、以下の少なくとも一つの変更が可能である。 [Modification]
At least one of the following changes can be made to the exterior component mounting structure 1 of the first embodiment described above.

（１）車体を変更する。
ここでの車体とは、走行風を受ける箇所を構成するものとする。走行風を受ける箇所として、例えば、フロントフェンダー、ボンネット、ルーフ、フロントドア、リアドア、リアフェンダー、アッパーレール、リアバンパー、フロントピラー、センターピラー、バックドア、トランクリッド、フロアパネル、ロッカーパネル等が挙げられる。かつ、ここでの車体とは、外装部品の取付箇所を有するものとする。外装部品の取付箇所を有するものとして、代表的には、上述の各部位におけるアウタパネルやカバー等が挙げられる。 (1) Change the vehicle body.
Here, the vehicle body constitutes a portion that receives the traveling wind. Examples of the location where the traveling wind is received include front fender, hood, roof, front door, rear door, rear fender, upper rail, rear bumper, front pillar, center pillar, back door, trunk lid, floor panel, rocker panel, and the like. Can be In addition, the vehicle body here has an attachment part for an exterior component. Representatively, the outer panel, the cover, and the like at each of the above-mentioned portions are provided as portions having attachment portions for the exterior components.

（２）外装部品を変更する。
例えば、バンパーカバーに取り付けられる外装部品として、上述のグリル３ｇ、その他、ヘッドライトやイルミネーションランプ、各種センサ等を取り付けるベゼル、ガーニッシュ、フロントスポイラー等が挙げられる。
例えば、フロントドアやリアドアのアウタパネルに取り付けられる外装部品として、サイドストーンガード等が挙げられる。
その他の外装部品として、サイドモール、リヤスポイラー、ルーフレール、アンテナカバー、フェンダーアーチモール、エンジンアンダーカバー、フロアアンダーカバー等が挙げられる。 (2) Change the exterior parts.
For example, as the exterior parts attached to the bumper cover, the above-described grille 3g, bezels, garnishes, front spoilers, etc. for attaching headlights, illumination lamps, various sensors, and the like can be given.
For example, as an exterior component attached to the outer panel of the front door or the rear door, there is a side stone guard or the like.
Other exterior parts include side moldings, rear spoilers, roof rails, antenna covers, fender arch moldings, engine undercovers, floor undercovers, and the like.

（３）取付片の先端部と台座部とが独立した部材である。
この形態の具体例として、台座部は外装部品の裏面に一体成形されており、先端部は台座部に対して着脱自在なクリップであることが挙げられる。
この形態の台座部、及びクリップは公知の構成を利用できる（例、特許文献２の図１参照）。台座部は、例えば、実施形態１で説明した台座部２３と同様に、一対の側壁部、連結壁部、天井部を備える有底筒状であることが挙げられる。台座部の天井部には、クリップの首部が嵌め込まれる切欠を有する。台座部にクリップが取り付けられた状態では、天井部の切欠がクリップで塞がれるものの、側壁部の周縁等で形成される開口は塞がれず、開口したままである。この台座部の開口を車体のリブで塞ぐことで、実施形態１と同様に、台座部内への走行風の侵入に起因する空間共鳴の発生を防止できる。その結果、上記空間共鳴に起因する異音の発生を低減できる。 (3) The tip of the mounting piece and the pedestal are independent members.
As a specific example of this mode, the pedestal portion is formed integrally with the back surface of the exterior component, and the distal end portion is a clip detachable from the pedestal portion.
Known configurations can be used for the pedestal portion and the clip in this mode (for example, see FIG. 1 of Patent Document 2). The pedestal portion is, for example, a bottomed cylindrical shape having a pair of side wall portions, a connecting wall portion, and a ceiling portion, similarly to the pedestal portion 23 described in the first embodiment. The ceiling of the pedestal has a notch into which the neck of the clip is fitted. In the state where the clip is attached to the pedestal portion, the notch in the ceiling portion is closed by the clip, but the opening formed by the peripheral edge of the side wall portion is not closed and remains open. By closing the opening of the pedestal portion with the rib of the vehicle body, it is possible to prevent the occurrence of spatial resonance due to the intrusion of the traveling wind into the pedestal portion, as in the first embodiment. As a result, generation of abnormal noise due to the spatial resonance can be reduced.

（４）台座部が内外に抜ける貫通孔を備える。
台座部の貫通孔は、例えば連結壁部等に設けたり（類似の構成として、特許文献２の図１参照）、連結壁部の周縁と外装部品の裏面との間に隙間を設けたりすることで形成することが挙げられる。貫通孔を備えることで、取付片の軽量化及び材料の低減、ひいては外装部品の軽量化、材料コストの低減を図れる。但し、台座部の内外に抜ける貫通孔を備えると、上述の外装部品の周縁と車体との隙間から侵入した風が貫通孔から台座部内を経て台座部の開口に抜ける、又はその逆に抜けることが考えられる。車体にリブを備えることで、このような走行風の通り抜けを防止できる。また、上記隙間から侵入した風が台座部内を通過する際に、流速を低減できる。これらのことから、台座部に貫通孔がある場合には、走行風の通り抜けに起因する風切り異音の発生を低減できると期待される。更に、上述の走行風の通り抜けを防止することで、走行風の通り抜け（吹き出し）に起因する車両表面からの走行風の剥離を防止できる。特に、車体がフロントバンパーカバーであれば、上記走行風の車両表面からの剥離防止によって、空力特性（Ｃｄ値）の向上が期待できる。上述のフォグランプ４等の光源からの光漏れも防止できる。 (4) The pedestal is provided with a through hole that passes through the inside and outside.
The through hole of the pedestal portion may be provided in, for example, a connecting wall portion (for a similar configuration, see FIG. 1 of Patent Document 2), or a gap may be provided between the periphery of the connecting wall portion and the back surface of the exterior component. To form. By providing the through holes, the weight of the mounting piece and the material can be reduced, and the weight of the exterior component and the material cost can be reduced. However, if a through hole is provided inside and outside the pedestal portion, the wind that has entered from the gap between the peripheral edge of the exterior component and the vehicle body passes through the through hole into the opening of the pedestal portion through the pedestal portion, or vice versa. Can be considered. By providing the ribs on the vehicle body, it is possible to prevent such a passage of the traveling wind. Further, when the wind that has entered through the gap passes through the pedestal portion, the flow velocity can be reduced. From these facts, when there is a through-hole in the pedestal portion, it is expected that generation of abnormal wind noise caused by passage of the traveling wind can be reduced. Further, by preventing the above-described traveling wind from passing through, it is possible to prevent the traveling wind from separating from the vehicle surface due to the traveling wind passing through (blowing out). In particular, if the vehicle body is a front bumper cover, improvement in aerodynamic characteristics (Cd value) can be expected by preventing the traveling wind from separating from the vehicle surface. Light leakage from a light source such as the fog lamp 4 described above can also be prevented.
