Description

この発明は、開閉ドア用シール材に関し、詳しくは、車体パネルのドア用開口縁部と、この開口縁部に開閉可能に取り付けられる開閉ドア（フロントドア、リアドア等）との間をシールするために、開閉ドアのドアパネル周縁部に取り付けられる開閉ドア用シール材（ドアウエザーストリップとも呼ばれることがある長尺なシール材、以下簡略的にシール材とも言う）に関する。 The present invention relates to an opening / closing door sealing material, and more specifically, to seal between a door opening edge of a vehicle body panel and an opening / closing door (front door, rear door, etc.) attached to the opening edge so as to be opened and closed. In particular, the present invention relates to an opening / closing door sealing material (a long sealing material sometimes referred to as a door weather strip, hereinafter simply referred to as a sealing material) attached to the peripheral edge of the door panel of the opening / closing door.

従来、車体パネルのドア用開口縁部と、この開口縁部に開閉可能に取り付けられる開閉ドアとの間をシールするための開閉ドア用シール材において、ドアパネルのリテーナに取り付けられる基部と、この基部から車体パネルの開口縁部に向けて突出された中空状のシール部とを備えた構造のものが一般的である。このような構造の開閉ドア用シール材においては、例えば、高圧洗車時等の車外側からの圧力がシール材に作用すると、シール材とドアパネルの側壁面やリテーナとの間に隙間が生じることがある。この場合、洗浄水が前記隙間を通って車室内側に浸入する、いわゆる潜り水が生じるという問題点がある。このような不具合を防止するために、シール材（ウエザーストリップ）の基部（基底部）の車外側部分に形成されたシールリップの付け根に、水漏れ防止シール部を突設したものがある（例えば、特許文献１参照）。また、基部（基底部）とシールリップ（背面リップ）との少なくとも一方に高発泡スポンジ層を設けることによって、ドア閉じ音をシール性を損なうことなく低減させるものもある（例えば、特許文献２参照）。 Conventionally, in an opening / closing door sealing material for sealing between a door opening edge of a vehicle body panel and an opening / closing door attached to the opening edge so as to be openable / closable, a base attached to a retainer of the door panel, and the base A structure having a hollow seal portion projecting from an opening edge portion of the vehicle body panel to the vehicle body panel is generally used. In the sealing material for an open / close door having such a structure, for example, when pressure from the outside of the vehicle, such as during high-pressure car washing, acts on the sealing material, a gap may be generated between the sealing material and the side wall surface of the door panel or the retainer. is there. In this case, there is a problem that so-called diving water is generated in which the cleaning water enters the vehicle interior through the gap. In order to prevent such inconvenience, there is one in which a water leak prevention seal portion is provided at the base of the seal lip formed on the vehicle outer side portion of the base portion (base portion) of the seal material (weather strip) (for example, , See Patent Document 1). In addition, there is also one that reduces the door closing sound without impairing the sealing performance by providing a high foamed sponge layer on at least one of the base (base) and the seal lip (back lip) (see, for example, Patent Document 2). ).

ところで、特許文献１に開示されたものにおいては、ドアパネル（リテーナ部分も含む）の建て付けや、シール材の組付けの「ばらつき」等によって、ドアパネルに対する水漏れ防止シール部の接触状態が変化して部分的な密着不良が発生しやすい。また、特許文献２に開示されたものにおいても、ドアパネルに対するシールリップの接触状態が変化しやすい。そして、前記変化を高発泡スポンジ層の弾性変形によって吸収することが困難で部分的な密着不良が発生しやすい。 By the way, in what was disclosed by patent document 1, the contact state of the water leak prevention seal part with respect to a door panel changes by the erection of a door panel (a retainer part is also included), the "variation" of the assembly | attachment of a sealing material, etc. And partial adhesion failure is likely to occur. Moreover, also in what was disclosed by patent document 2, the contact state of the seal lip with respect to a door panel tends to change. And it is difficult to absorb the change by elastic deformation of the highly foamed sponge layer, and partial adhesion failure tends to occur.

この発明の目的は、前記問題点に鑑み、ドアパネルに対する密着性の向上を図ることができ、その結果、シール性を良好に維持することができる開閉ドア用シール材を提供することである。 In view of the above problems, an object of the present invention is to provide an open / close door sealing material that can improve adhesion to a door panel and, as a result, can maintain good sealing performance.

前記課題を解決するために、この発明の請求項１に係る開閉ドア用シール材は、車体パネルのドア用開口縁部と、この開口縁部に開閉可能に取り付けられる開閉ドアとの間をシールするために、前記開閉ドアのドアパネル周縁部に取り付けられる長尺な開閉ドア用シール材であって、前記シール材は、前記ドアパネルに取り付けられる基部と、取付状態で前記基部の車内寄り部分から前記車体パネルの開口縁部に向けて突出し、かつ前記車体パネルの開口縁部と接触可能に前記基部と一体に形成されると共に横断面中空形状であって中空部を構成する周壁部のうち車内側周壁部の肉厚が車外側周壁部の肉厚よりも厚く形成された第１シール部と、前記基部の車外寄り部分から前記車体パネルの開口縁部に向けて突出し、かつ前記車体パネルの開口縁部と接触可能な第２シール部と、この第２シール部から前記ドアパネルの側壁面に向けて突出し、かつ前記ドアパネルの側壁面と接触する第３シール部と、前記基部の車外寄り部分に形成されかつ前記ドアパネルの下側壁部に弾接する第４シール部とを備え、前記第３シール部の先端側部分は、前記第１シール部が車体パネルに弾接して弾性変形することにより、屈曲した第２シール部の方向へ変位して前記第２シール部を介してドアパネルの側壁面側へ押圧する高発泡スポンジゴムにより一体成形されかつ横断面矩形に形成され、ドアパネルの側壁面に弾接する先端面が平坦面をなしている容易変形部を有し、前記第２シール部が取付状態で幅方向の中央部が車内側へ突出する横断面Ｌ字状に形成され、突出した屈曲部の部分が屈曲可能とされ、前記開閉ドアの閉時に前記車体パネルに圧接されて屈曲することにより、前記第３シール部が前記ドアパネルの側壁面の方向へ押圧されることで、前記容易変形部の先端が前記第２シール部の押圧力が加わった大きな力で前記ドアパネルの側壁面に圧接されると共に、幅方向に押し広がることを特徴とする。 In order to solve the above-mentioned problem, a door sealing material according to claim 1 of the present invention seals between a door opening edge of a vehicle body panel and an opening / closing door attached to the opening edge so as to be opened and closed. In order to do so, a long opening / closing door sealing material attached to a door panel peripheral portion of the opening / closing door, wherein the sealing material includes a base portion attached to the door panel and an inboard portion of the base portion in an attached state. It protrudes toward the opening edge portion of the vehicle body panel, and among vehicles inside the peripheral wall portion constituting the contactable with said the opening edge portion of the vehicle body panel is formed in the base and integrally a Rutotomoni cross sectional hollow shape hollow portion A first seal portion formed to have a thickness of the peripheral wall portion thicker than a thickness of the outer peripheral wall portion of the vehicle body; a portion projecting toward the opening edge of the vehicle body panel from a vehicle outer portion of the base portion; A second sealing portion capable of contacting with the rim, and a third sealing portion that contacts the second sealing portion protrudes toward the side wall surface of the door panel, and the side wall surface of the door panel, exterior portion near the base portion And a fourth seal portion that elastically contacts the lower side wall portion of the door panel, and the tip side portion of the third seal portion is elastically deformed by the first seal portion elastically contacting the vehicle body panel, It is integrally formed of a highly foamed sponge rubber that is displaced in the direction of the bent second seal portion and presses against the side wall surface side of the door panel via the second seal portion, and is formed into a rectangular cross section, and is elastic on the side wall surface of the door panel. A bent portion that has an easily deformable portion whose front end surface is a flat surface , the second seal portion is in an attached state, and is formed in an L-shaped cross section in which a central portion in the width direction protrudes toward the vehicle interior side. Is bent Is a capability, by bending is pressed against the vehicle body panel closing of the door, that the third sealing portion is pressed toward the side wall surface of the door panel, the tip of the easily deformable portion is the The second seal portion is pressed against the side wall surface of the door panel with a large force applied with the pressing force of the second seal portion, and pushes and spreads in the width direction.

前記構成によると、ドア閉時に第２シール部が車体パネルに圧接されて屈曲することにより、第３シール部がドアパネルの側壁面の方向へ押圧される。これによって、容易変形部の先端が第２シール部の押圧力が加わった大きな力でドアパネルの側壁面に圧接されると共に、幅方向に押し広がるため、ドアパネルに対する容易変形部の密着性が確保される。
前記したようにして、ドアパネルに対する容易変形部の密着性を確保することによって、ドアパネル（リテーナ部分も含む）の建て付けや、シール材の組付けの「ばらつき」等があったとしても、その「ばらつき」等を高発泡スポンジゴムによりなる容易変形部の弾性変形によって良好に吸収することができる。この結果、シール材のドアパネルに対する密着性の向上を図ることができ、シール性を長期間にわたって良好に維持することができる。
また、前記基部の車外寄り部分に形成されかつ前記ドアパネルの下側壁部に弾接する第４シール部を備えたので第３シール部とドアパネルの側壁部との隙間から雨水等が浸入した場合でも、それ以上車内側へ浸入するのを防止することができる。
また、ドア閉時に横断面中空形状の第１シール部が車体パネルに面接触状態で弾接し、屈曲した第２シール部の方向へ良好に弾性変形する。このため、第１シール部が車体パネルと適正な力で弾接すると共に、第２シール部をドアパネルの側壁面の方向へ押圧することができる。また、第１シール部の中空部を構成する周壁部のうち車内側周壁部の肉厚を車外側周壁部の肉厚よりも厚く形成したので第１シール部の剛性を高めることができる。
また、ドア閉時に第２シール部が車体パネルに圧接されて屈曲すると共に、第１シール部が車体パネルに弾接して屈曲した第２シール部の方向へ変位（弾性変形）する。そして、第１シール部による押圧力が第２シール部に加わり、第３シール部を第１シール部による押圧力の分だけ大きい力でドアパネルの側壁面側へ押圧する。これによって、第３シール部の容易変形部の先端が第２シール部の押圧力が加わった大きな力でドアパネルの側壁面に圧接されると共に、幅方向に押し広がるように良好に弾性変形する。この結果、ドアパネルの側壁面に対する容易変形部の接触面積が増大する。したがって、シール材のドアパネルに対する密着性の向上を図ることができる。
また、第１シール部の車内側周壁部が車体パネルの開口縁部の側壁部に押圧される際に波打つことなく面接触状態を保って弾性変形して密着すると共に、車外側周壁部を第２シール部の方向へ不足のない量で変位させ第２シール部を車外側方向へ押圧することができる。
また、ドア閉時に第２シール部が車体パネルに圧接される際、第２シール部は、幅方向の中央部の屈曲部において容易に弾性変形して屈曲し、これによって、第３シール部をドアパネルの側壁面の方向へ良好に押圧する。したがって、第３シール部をドアパネルの側壁面の方向へ良好に押圧して、容易変形部の先端をドアパネルの側壁面に適切な力で密着させることできる。これによって、ドアパネルに対して容易変形部を密着させシール材のシール性の向上を図ることができる。
さらに、横断面矩形に形成された容易変形部の先端面の平坦面がドアパネルの側壁面に面接触状態で安定よく密着する。したがってドアパネルに対するシール材のシール性の向上に効果が大きい。 According to the said structure, a 3rd seal part is pressed to the direction of the side wall surface of a door panel by a 2nd seal part being pressed and bent to a vehicle body panel at the time of a door closing. As a result, the tip of the easily deformable portion is pressed against the side wall surface of the door panel with a large force applied by the pressing force of the second seal portion, and is pushed and spread in the width direction, thereby ensuring the adhesion of the easily deformable portion to the door panel. The
As described above, by ensuring the adhesion of the easily deformable portion to the door panel, even if there is "variation" in the installation of the door panel (including the retainer portion) or the assembly of the sealing material, the " The “variation” and the like can be satisfactorily absorbed by the elastic deformation of the easily deformable portion made of highly foamed sponge rubber. As a result, the adhesion of the sealing material to the door panel can be improved, and the sealing performance can be maintained well over a long period of time.
In addition, since the fourth seal portion that is formed on the vehicle outer portion of the base portion and elastically contacts the lower wall portion of the door panel is provided, even when rainwater or the like enters from the gap between the third seal portion and the side wall portion of the door panel, Further intrusion to the inside of the vehicle can be prevented.
Further, when the door is closed, the first seal portion having a hollow cross section is elastically contacted with the vehicle body panel in a surface contact state, and is elastically deformed well in the direction of the bent second seal portion. For this reason, the first seal portion can elastically contact the vehicle body panel with an appropriate force, and the second seal portion can be pressed toward the side wall surface of the door panel. Moreover, since the wall thickness of the vehicle inner peripheral wall portion of the peripheral wall portions constituting the hollow portion of the first seal portion is formed to be thicker than the wall thickness of the vehicle outer peripheral wall portion, the rigidity of the first seal portion can be increased.
Further, when the door is closed, the second seal portion is pressed against the vehicle body panel and bent, and the first seal portion is displaced (elastically deformed) toward the bent second seal portion by elastic contact with the vehicle body panel. Then, the pressing force by the first seal portion is applied to the second seal portion, and the third seal portion is pressed to the side wall surface side of the door panel with a force that is larger by the pressing force by the first seal portion. As a result, the tip of the easily deformable portion of the third seal portion is pressed against the side wall surface of the door panel with a large force applied by the pressing force of the second seal portion, and is elastically deformed well so as to be pushed and spread in the width direction. As a result, the contact area of the easily deformable portion with respect to the side wall surface of the door panel increases. Therefore, it is possible to improve the adhesion of the sealing material to the door panel.
Further, when the vehicle inner peripheral wall portion of the first seal portion is pressed against the side wall portion of the opening edge portion of the vehicle body panel, it is elastically deformed and brought into close contact without undulation, and the vehicle outer peripheral wall portion is It is possible to displace the second seal portion in the direction of the two seal portions by a sufficient amount and press the second seal portion toward the vehicle outer side.
Further, when the second seal portion is pressed against the vehicle body panel when the door is closed, the second seal portion is easily elastically deformed and bent at the bent portion at the central portion in the width direction. Press well in the direction of the side wall surface of the door panel. Therefore, the third seal portion can be pressed well in the direction of the side wall surface of the door panel, and the tip of the easily deformable portion can be brought into close contact with the side wall surface of the door panel with an appropriate force. As a result, the easily deformable portion can be brought into close contact with the door panel to improve the sealing performance of the sealing material.
Furthermore, the flat surface of the front end surface of the easily deformable portion formed in a rectangular cross section is stably adhered to the side wall surface of the door panel in a surface contact state. Therefore, the effect of improving the sealing performance of the sealing material with respect to the door panel is great.

第３シール部６０は、第２シール部５５の根元部近傍からドアパネル２０のリテーナ２４近傍の側壁部（側壁面）２３に向けて突出し、ドアパネル２０の側壁部２３と接触する。図２と図４に示すように、第３シール部６０の先端側部分は、高発泡スポンジゴムにより一体成形された容易変形部６２となっている。図４に示すように、容易変形部６２は横断面矩形に形成され、ドアパネル２０のリテーナ２４の近傍の側壁部（側壁面）２３に弾接する先端面が平坦面をなしている。また、容易変形部６２は、その横断面において根元部が幅広で、先端部に向かって逐次幅狭となった横断面台形状に形成されているが、根元部と先端部の幅が同等又は根元部が幅狭で先端部が幅広であってもよい。そして、図２に示すように、サッシュドア１１の閉時に第２シール部５５が車体パネル１の開口縁部２の周壁部３に圧接されて屈曲すると共に、第１シール部５０が車体パネル１の開口縁部２の側壁部４に弾接して弾性変形することにより、屈曲した第２シール部５５の方向へ変位して第２シール部５５を車外側方向へ押圧し、その結果、第３シール部６０をドアパネル２０のリテーナ２４近傍の側壁部２３側へ押圧することで、容易変形部６２の先端が第１シール部５０の押圧力が加わると共に、第２シール部５５の押圧力が加わった大きな力でドアパネル２０の側壁部２３に圧接されて幅方向に押し広がる。 The third seal portion 60 protrudes from the vicinity of the base portion of the second seal portion 55 toward the side wall portion (side wall surface) 23 in the vicinity of the retainer 24 of the door panel 20 and contacts the side wall portion 23 of the door panel 20. As shown in FIGS. 2 and 4, the tip side portion of the third seal portion 60 is an easily deformable portion 62 that is integrally formed of a highly foamed sponge rubber. As shown in FIG. 4, the easily deformable portion 62 is formed in a rectangular shape in cross section, and the front end surface that elastically contacts the side wall portion (side wall surface) 23 in the vicinity of the retainer 24 of the door panel 20 forms a flat surface. Further, the easily deformable portion 62 is formed in a trapezoidal shape having a wide base at the cross section and gradually narrowing toward the tip, but the width of the root and the tip is equal or The root portion may be narrow and the tip portion may be wide. As shown in FIG. 2, when the sash door 11 is closed, the second seal portion 55 is pressed against the peripheral wall portion 3 of the opening edge 2 of the vehicle body panel 1 and bent, and the first seal portion 50 is connected to the vehicle body panel 1. Is elastically deformed by elastic contact with the side wall 4 of the opening edge 2 of the opening 2 and is displaced in the direction of the bent second seal portion 55 to press the second seal portion 55 in the vehicle outer direction. By pressing the seal portion 60 toward the side wall portion 23 in the vicinity of the retainer 24 of the door panel 20, the front end of the easily deformable portion 62 applies the pressing force of the first seal portion 50 and the pressing force of the second seal portion 55 is applied. It is pressed against the side wall 23 of the door panel 20 with a large force and spreads in the width direction.

また、容易変形部６２を形成する高発泡スポンジゴム（例えば、ＥＰＤＭスポンジゴム）の密度は、０．１０〜０．４０ｇ／ｃｍ^３に設定されことが好ましく、０．２５±０．１０ｇ／ｃｍ^３に設定されることがより好ましい。また、シール材をなす第１成形体３２の容易変形部６２以外の発泡スポンジゴムの部分（例えば、ＥＰＤＭスポンジゴム）の密度は、０．４０〜０．７０ｇ／ｃｍ^３に設定されることが好ましく、０．５５±０．１０ｇ／ｃｍ^３に設定されることがより好ましい。そして、シール材組立体３０を構成する第１成形体３２は共押出成形により一体成形されている。 The density of the highly foamed sponge rubber (for example, EPDM sponge rubber) that forms the easily deformable portion 62 is preferably set to 0.10 to 0.40 g / cm ³ , and is 0.25 ± 0.10 g / cm 3. More preferably, it is set to ³ . Further, the density of the foamed sponge rubber portion (for example, EPDM sponge rubber) other than the easily deformable portion 62 of the first molded body 32 forming the sealing material may be set to 0.40 to 0.70 g / cm ^3. Preferably, it is more preferably set to 0.55 ± 0.10 g / cm ³ . And the 1st molded object 32 which comprises the sealing material assembly 30 is integrally molded by coextrusion molding.

また、シール材組立体３０の第２成形体３３は、基部と、横断面中空状の第１シール部とがそれぞれ形成されているが、第２シール部５５及び第３シール部６０は形成されていない。また、サッシュドア１１の本体部分を構成するドアパネル２０の下側縁部１９及び前側縦縁部１６にはリテーナが設けられていないため、複数の取付孔（図示しない）が配設され、それらの箇所に対応する第２成形体３３の基部（図示しない）には、複数のクリップ（図示しない）が長手方向に所定間隔をたもって配設される。そして、第２成形体３３は、その複数のクリップがドアパネル２０の複数の取付孔に差し込まれて係合されることによって、ドアパネル２０の下側縁部１９及び前側縦縁部１６に沿って装着される。 Further, the second molded body 33 of the sealing material assembly 30 is formed with a base portion and a first seal portion having a hollow cross section, but the second seal portion 55 and the third seal portion 60 are formed. Not. Moreover, since the retainer is not provided in the lower edge part 19 and the front side vertical edge part 16 of the door panel 20 which comprise the main-body part of the sash door 11, several attachment holes (not shown) are arrange | positioned, those A plurality of clips (not shown) are arranged at predetermined intervals in the longitudinal direction at the base (not shown) of the second molded body 33 corresponding to the location. The second molded body 33 is mounted along the lower edge 19 and the front vertical edge 16 of the door panel 20 by engaging the plurality of clips inserted into the plurality of mounting holes of the door panel 20. Is done.

この実施例１に係る開閉ドア用シール材は上述したように構成される。したがって、サッシュドア１１のドア閉時に、シール材としての第１成形体３２の第２シール部５５が車体パネル１の開口縁部２の周壁部３に圧接されて屈曲することにより、第３シール部６０がドアパネル２０のリテーナ２４近傍の側壁部（側壁面）２３の方向へ押圧される。これによって、容易変形部６２の先端が、第２シール部５５の押圧力が加わった大きな力でドアパネル２０の側壁部２３に圧接されると共に、幅方向に押し広がる。このため、ドアパネル２０の側壁部２３に対する容易変形部６２の密着性が良好に確保される。前記したようにして、ドアパネル２０の側壁部２３に対する容易変形部６２の密着性を良好に確保することによって、ドアパネル２０の建て付けや、シール材としての第１成形体３２の組付けの「ばらつき」等があったとしても、前記「ばらつき」を高発泡スポンジゴムによりなる容易変形部６２の弾性変形によって良好に吸収することができる。この結果、シール材としての第１成形体３２のドアパネル２０の側壁部２３に対する密着性の向上を図ることができ、その結果、シール性を長期間にわたって良好に維持することができる。 The opening / closing door sealing material according to the first embodiment is configured as described above. Therefore, when the door of the sash door 11 is closed, the second seal portion 55 of the first molded body 32 as a seal material is pressed against the peripheral wall portion 3 of the opening edge portion 2 of the vehicle body panel 1 and is bent, whereby the third seal The portion 60 is pressed toward the side wall portion (side wall surface) 23 in the vicinity of the retainer 24 of the door panel 20. As a result, the tip of the easily deformable portion 62 is pressed against the side wall portion 23 of the door panel 20 with a large force to which the pressing force of the second seal portion 55 is applied, and also spreads in the width direction. For this reason, the adhesiveness of the easily deformable part 62 with respect to the side wall part 23 of the door panel 20 is ensured favorably. As described above, by ensuring good adhesion of the easily deformable portion 62 with respect to the side wall portion 23 of the door panel 20, “variation” of the installation of the door panel 20 and the assembly of the first molded body 32 as a sealing material is performed. ”And the like, the“ variation ”can be satisfactorily absorbed by the elastic deformation of the easily deformable portion 62 made of highly foamed sponge rubber. As a result, it is possible to improve the adhesion of the first molded body 32 as the sealing material to the side wall portion 23 of the door panel 20, and as a result, it is possible to maintain the sealing performance well over a long period of time.

この実施例１において、サッシュドア１１のドア閉時に、第２シール部５５が車体パネル１の開口縁部２の周壁部３に圧接されて屈曲部５７において容易に弾性変形して屈曲すると共に、第１シール部５０が車体パネル１の開口縁部２の側壁部４に弾接し、これによって前記屈曲した第２シール部５５の方向へ変位（弾性変形）する。そして、第１シール部５０による押圧力が第２シール部５５に加わり、第３シール部６０を第１シール部５０による押圧力の分だけ大きい力でドアパネル２０の側壁部２３側へ押圧する。これによって、第３シール部６０の容易変形部６２の先端がドアパネル２０の側壁部２３に圧接して幅方向へ大きく押し広がる。この結果、ドアパネル２０の側壁部２３に対する容易変形部６２の接触面積が増大するため、ドアパネル２０の側壁部２３に対する容易変形部６２の密着性の向上を良好に図ることができる。 In the first embodiment, when the sash door 11 is closed, the second seal portion 55 is pressed against the peripheral wall portion 3 of the opening edge portion 2 of the vehicle body panel 1 and is easily elastically deformed and bent at the bent portion 57. The first seal portion 50 is elastically contacted with the side wall portion 4 of the opening edge portion 2 of the vehicle body panel 1, thereby being displaced (elastically deformed) in the direction of the bent second seal portion 55. Then, the pressing force by the first seal portion 50 is applied to the second seal portion 55, and the third seal portion 60 is pressed to the side wall portion 23 side of the door panel 20 with a force that is larger by the pressing force by the first seal portion 50. As a result, the tip of the easily deformable portion 62 of the third seal portion 60 is pressed against the side wall portion 23 of the door panel 20 and greatly spreads in the width direction. As a result, since the contact area of the easily deformable portion 62 with respect to the side wall portion 23 of the door panel 20 increases, the adhesion of the easily deformable portion 62 to the side wall portion 23 of the door panel 20 can be improved satisfactorily.

また、この実施例１において、容易変形部６２を形成する高発泡スポンジゴムの密度が、０．１０〜０．４０（より好ましくは０．１５〜０．３５）ｇ／ｃｍ^３とされ、シール材を構成する第１成形体３２の容易変形部６２以外の部分の密度が、０．４０〜０．７０（より好ましくは０．４５〜０．６５）ｇ／ｃｍ^３とされることで、ドア閉時の第１、第２シール部５０、５５の弾性変形に伴う反力を適切な大きさにすることができると共に、容易変形部６２を容易に変形させて先端を幅方向に押し広がらせてドアパネル２０の側壁部２３に良好に密着させることができる。すなわち、容易変形部６２を形成する高発泡スポンジゴムの密度が０．１０（より好ましくは０．１５）ｇ／ｃｍ^３よりも小さく設定されると、ドアパネル２０の側壁部２３に対する容易変形部６２の押圧力が不足して密着性が確保できない不具合が想定され、高発泡スポンジゴムの密度が０．４０（より好ましくは０．３５）ｇ／ｃｍ^３よりも大きく設定されると、容易変形部６２が弾性変形し難くなり、ドア閉時に第１シール部５０や第２シール部５５に押圧されて容易に弾性変形して車体パネル１の側壁部４に良好に密着させることが困難となる不具合が想定される。さらに、第１成形体３２の容易変形部６２以外の部分の密度が０．４０（より好ましくは０．４５）ｇ／ｃｍ^３よりも小さく設定されると、車体パネル１に開口縁部２に対する第１、第２シール部５０、５５の押圧力が不足して、車体パネル１の開口縁部２の周壁部３及び側壁部４と、第１、第２シール部５０、５５とのシール性が低下する不具合が想定され、第１成形体３２の容易変形部６２以外の部分の密度が０．７０（より好ましくは０．６５）ｇ／ｃｍ^３よりも大きく設定されると、車体パネル１の開口縁部２に対する第１、第２シール部５０、５５の弾発力が大きくなり、サッシュドア１１のドア閉めに要する力が過大となる不具合が想定される。前記したように、第１成形体３２の容易変形部６２の密度及び容易変形部６２以外の部分の密度が設定されることによって前記各不具合の発生を防止することができる。この結果、サッシュドア１１のドア閉めに要する力を適切に確保しながらドアパネル２０に対する密着性の向上をより一層良好に図ることができる。 In Example 1, the density of the highly foamed sponge rubber forming the easily deformable portion 62 is 0.10 to 0.40 (more preferably 0.15 to 0.35) g / cm ^3, and the seal The density of the portion other than the easily deformable portion 62 of the first molded body 32 constituting the material is 0.40 to 0.70 (more preferably 0.45 to 0.65) g / cm ³ , The reaction force accompanying the elastic deformation of the first and second seal portions 50 and 55 when the door is closed can be set to an appropriate magnitude, and the easily deformable portion 62 can be easily deformed to push the tip in the width direction. It is possible to satisfactorily adhere to the side wall 23 of the door panel 20. That is, when the density of the highly foamed sponge rubber forming the easily deformable portion 62 is set to be smaller than 0.10 (more preferably 0.15) g / cm ^{3, the} easily deformable portion 62 with respect to the side wall portion 23 of the door panel 20 is set. If the density of the highly foamed sponge rubber is set to be larger than 0.40 (more preferably 0.35) g / cm ³ , an easily deformable portion is assumed. 62 becomes difficult to be elastically deformed, and is easily pressed elastically by the first seal portion 50 and the second seal portion 55 when the door is closed, making it difficult to make good contact with the side wall portion 4 of the vehicle body panel 1. Is assumed. Furthermore, when the density of the portion other than the easily deformable portion 62 of the first molded body 32 is set to be smaller than 0.40 (more preferably 0.45) g / cm ³ , the vehicle body panel 1 has a shape relative to the opening edge portion 2. Due to insufficient pressing force of the first and second seal portions 50 and 55, the sealing performance between the peripheral wall portion 3 and the side wall portion 4 of the opening edge portion 2 of the vehicle body panel 1 and the first and second seal portions 50 and 55. If the density of the portion other than the easily deformable portion 62 of the first molded body 32 is set to be greater than 0.70 (more preferably 0.65) g / cm ³ , the vehicle body panel 1 It is assumed that the resilience of the first and second seal portions 50 and 55 with respect to the opening edge portion 2 increases and the force required to close the door of the sash door 11 becomes excessive. As described above, by setting the density of the easily deformable portion 62 of the first molded body 32 and the density of portions other than the easily deformable portion 62, the occurrence of each of the above problems can be prevented. As a result, the adhesion to the door panel 20 can be further improved while ensuring the force required to close the sash door 11 appropriately.

また、この実施例１において、ドア閉時に、横断面中空形状の第１シール部５０が車体パネル１の開口縁部２の側壁部４に面接触状態で弾接して弾性変形し、屈曲した第２シール部５５の方向へ良好に変位する。このため、第１シール部５０が車体パネル１の開口縁部２の側壁部４に適正な力で弾接すると共に、第２シール部５５を車外側方向へ押圧するので密着性の向上に効果が大きい。さらに、ドア閉時に第２シール部５５が車体パネル１の開口縁部２の周壁部３に圧接される際、第２シール部５５は、幅方向の中央部の屈曲部５７において容易に弾性変形して屈曲し、これによって、第３シール部６０をドアパネル２０の側壁部２３の方向へ良好に押圧する。このようにして、第３シール部６０をドアパネル２０の側壁部２３の方向へ良好に押圧して、容易変形部６２の先端をドアパネル２０の側壁部２３に大きな力で圧接させて幅方向に押し広げることができるため、ドアパネル２０の側壁部２３に対する容易変形部６２の密着性の向上を図ることができる。 Further, in the first embodiment, when the door is closed, the first seal portion 50 having a hollow cross section is elastically deformed by elastic contact with the side wall portion 4 of the opening edge portion 2 of the vehicle body panel 1 in a surface contact state, and is bent. 2 Displaces well in the direction of the seal portion 55. For this reason, the first seal portion 50 is elastically contacted with the side wall portion 4 of the opening edge portion 2 of the vehicle body panel 1 with an appropriate force, and the second seal portion 55 is pressed in the vehicle outer side direction, which is effective in improving the adhesion. large. Further, when the second seal portion 55 is pressed against the peripheral wall portion 3 of the opening edge portion 2 of the vehicle body panel 1 when the door is closed, the second seal portion 55 is easily elastically deformed at the bent portion 57 at the central portion in the width direction. Thus, the third seal portion 60 is favorably pressed toward the side wall portion 23 of the door panel 20. In this way, the third seal portion 60 is pressed well in the direction of the side wall portion 23 of the door panel 20, and the front end of the easily deformable portion 62 is pressed against the side wall portion 23 of the door panel 20 with a large force and pushed in the width direction. Since it can be expanded, the adhesion of the easily deformable portion 62 to the side wall portion 23 of the door panel 20 can be improved.

また、この実施例１において、横断面矩形（台形状）に形成された容易変形部６２先端の平坦面がドアパネル２０の側壁部２３に面接触状態で安定よく弾接するため、ドアパネル２０の側壁部２３に対する容易変形部６２の密着性の向上に効果が大きい。 Further, in the first embodiment, the flat surface at the tip of the easily deformable portion 62 formed in a rectangular cross section (trapezoidal shape) makes a stable elastic contact with the side wall portion 23 of the door panel 20 in a surface contact state. The effect of improving the adhesion of the easily deformable portion 62 with respect to 23 is great.

また、サッシュドア１１のドアパネル２０のアウタパネル２２に設けられたリテーナ２４に対し、シール材を構成する第１成形体３２の基部４０が嵌込まれることによって、サッシュドア１１に第１成形体３２を容易に装着することができる。 Further, the base 40 of the first molded body 32 constituting the sealing material is fitted into the retainer 24 provided on the outer panel 22 of the door panel 20 of the sash door 11, so that the first molded body 32 is placed on the sash door 11. It can be easily installed.

また、この実施例１においては、第１、第２の両成形体３２、３３と、これら第１、第２の両成形体３２、３３を接合する第１、第２の接合体３４、３５によって環状をなすシール材組立体３０が構成される。そして、水が浸入しやすい部分（フロント側のサッシュドア１１のドアサッシュ部１３の上縁部１４及び前側傾斜部１５の部分）に、第１シール部５０と、第２シール部５５と、容易変形部６２を先端側に有する第３シール部６０とがそれぞれ形成された第１成形体３２を配置することによって、シール性を効率よく確保することができる。さらに、水が浸入し難い部分（サッシュドア１１の後側上縦縁部１７と後側下縦縁部１８と下側縁部１９及び前側縦縁部１６とにわたる部分）に、第２シール部５５及び第３シール部６０が形成されない第２成形体３３を配置してドア閉めに要する力を過大にすることなく適切な範囲に保つことができる。この結果、サッシュドア１１のシール性の向上とドア閉めに要する力を適切にすることに効果が大きい。なお、第２成形体３３にも、潜り水を防止するためのリップ（図示しない）が設けられている。 In Example 1, both the first and second molded bodies 32 and 33 and the first and second bonded bodies 34 and 35 that join the first and second molded bodies 32 and 33 are used. Thus, an annular sealing material assembly 30 is formed. The first seal portion 50 and the second seal portion 55 are easily formed on the portion where water easily enters (the upper edge portion 14 and the front inclined portion 15 of the door sash portion 13 of the front sash door 11). By arranging the first molded body 32 formed with the third seal portion 60 having the deformable portion 62 on the distal end side, it is possible to efficiently ensure the sealing performance. Further, the second seal portion is formed in a portion where water is difficult to enter (a portion extending between the rear upper vertical edge portion 17, the rear lower vertical edge portion 18, the lower edge portion 19, and the front vertical edge portion 16) of the sash door 11. The second molded body 33 in which the 55 and the third seal portion 60 are not formed can be arranged and kept in an appropriate range without excessively increasing the force required for closing the door. As a result, the effect of improving the sealing performance of the sash door 11 and making the force required for closing the door appropriate is great. The second molded body 33 is also provided with a lip (not shown) for preventing diving water.

The easily deformable portion 262 is formed in a rectangular cross section (trapezoidal shape), and the front end surface that elastically contacts the upper wall portion 223a of the side wall portion 223 of the door panel 220 forms a flat surface. Further, the density of the highly foamed sponge rubber (for example, EPDM sponge rubber) forming the easily deformable portion 262 is 0.10 to 0.40 (more preferably, 0.15 to. 35) g / cm ³ , and the density of the low foamed sponge rubber portion (for example, EPDM sponge rubber) other than the easily deformable portion 262 of the sealing material 231 is 0.40 to 0.70 (more preferably, 0.00. 45-0.65) g / cm ³ . The sealing material 231 is integrally formed by coextrusion molding.

この実施例２に係る開閉ドア用シール材は上述したように構成される。したがって、この実施例２においては、パネルドア２２１のドアパネル２２０の取付孔２２５に、シール材２３１の基部２４０のクリップ２７０が差し込まれて係合されることによって、パネルドア２２１にシール材２３１を容易に装着することができる。その他の構成は実施例１とほぼ同様にして構成されるため、実施例１と同様の作用効果を奏する。 The opening / closing door sealing material according to the second embodiment is configured as described above. Therefore, in the second embodiment, the clip 270 of the base 240 of the sealant 231 is inserted into and engaged with the mounting hole 225 of the door panel 220 of the panel door 221, so that the sealant 231 can be easily attached to the panel door 221. can do. Since other configurations are substantially the same as those of the first embodiment, the same effects as those of the first embodiment can be obtained.

また、実施例２においても、実施例１と同様にして、押出成形品である第１成形体と、第２成形体とが射出成形によって形成される第１、第２の両接合体によって接合されて環状に形成されたシール材組立体とすることも可能である。この場合、シール材２３１によって第１成形体が形成される。 Also in Example 2, as in Example 1, the first molded body and the second molded body, which are extrusion molded products, are joined by both the first and second joined bodies formed by injection molding. It is also possible to provide an annular seal material assembly. In this case, the first molded body is formed by the sealing material 231.
