【０００１】
【発明の属する技術分野】
本発明はヒンジ取付装置に係り、家具本体に扉体を開閉自在に取り付けるものに関する。
【０００２】
【従来の技術】
従来、この種のヒンジ取付装置としては、たとえば、特許第２６６０６５６号公報に記載されているように、ヒンジ基体の一端部に扉体の取付孔内に嵌合する嵌合突部及び前記取付孔の開口縁部に当接する当接板部を有する嵌合体を回動自在に設け、この嵌合体の両側部に前記取付孔の壁面に圧着する独立した締付け部材をそれぞれ設け、この両側部の締付け部材と前記嵌合体の両側部との間にこの両側部の締付け部材を拡開して前記取付孔の壁面にそれぞれ圧着させる拡開部材をそれぞれ上下動自在に配置し、前記嵌合体の当接板部にピンにてブラケットを回動自在に取り付けるとともに、このピンを介して前記ブラケットに前記両側部の拡開部材を保持し、前記当接板部上に前記ブラケットを閉回動時に前記ピンを介して前記両側部の拡開部材をそれぞれ引き上げてこの両側部の拡開部材にて前記両側部の締付け部材を拡開させて前記取付孔の壁面にそれぞれ圧着させる構成が知られている。
【０００３】
【発明が解決しようとする課題】
前記公報に記載の構成では、嵌合体の両側部に独立した締付け部材をそれぞれ設けるとともに、この両側部の締付け部材と前記嵌合体の両側部との間にブラケットの閉回動時に引き上げられ前記両側部の締付け部材を拡開させる拡開部材をそれぞれ上下動自在に配置するため、取付孔内に嵌合体を圧着させる部品点数が多く構成が複雑であり、これら部品相互の組付け操作に手数を要し、また、ブラケットのピン挿通部をブラケットの閉回動時に拡開部材を引き上げるように肉圧を変化させる特殊の構造に形成する必要がある、という問題がある。
【０００４】
本発明は、このような点に鑑みてなされたもので、嵌合体の当接板部にロックレバーを閉回動することにより、この嵌合体を扉体の取付孔に簡単にかつ確実に固定でき、この取付孔に嵌合体を固定する部品点数が少なく構成が簡単で、これら部品相互の組付け操作も容易であってコストメリットの大きいヒンジ取付装置を提供することを目的とするものである。
【０００５】
【課題を解決するための手段】
請求項１記載のヒンジ取付装置は、家具本体に固定されるヒンジ基体と、このヒンジ基体の一端部にリンクアームを介して回動自在に設けられ前記家具本体の扉体に形成された取付孔に固定して前記家具本体に前記扉体を開閉自在に取付ける取付手段と、を具備し、前記取付手段は、前記扉体の取付孔内に嵌合する嵌合突部を有するとともに前記取付孔の開口縁部に当接する当接板部を有する嵌合体と、この嵌合体にこの嵌合体から離間する方向に進出可能に設けられ先端部に前記取付孔の壁面に圧着する圧着部を有するロックプレートと、前記嵌合体の当接板部に回動自在に設けられこの当接板部上に閉回動時に前記ロックプレートの圧着部を前記取付孔の壁面に圧着させる方向にこのロックプレートを押動する押動突部を備えたロックレバーと、を有し、前記嵌合体の嵌合突部は、前記取付孔内の壁面に対向する両側部に前記ロックプレートを係合する係合面部をそれぞれ有し、前記ロックプレートは、前記嵌合突部の両側部の係合面部にそれぞれ進出可能に係合された両側部の係合板部と、この両側部の係合板部の一端部間に設けられ先端部に前記取付孔の壁面に圧着する圧着部を形成した圧着板部と、を有する、ものである。
【０００６】
そして、扉体の側縁部に対してヒンジ基体を交差する状態で、この扉体の取付孔内に嵌合体の嵌合突部を嵌合することにより、この嵌合体の当接板部が取付孔の開口縁部に当接される。このとき、ロックレバーは嵌合体の当接板部から開回動されて開いた状態になっている。
【０００７】
また、嵌合体の当接板部上に向かってロックレバーを閉回動することにより、このロックレバーの押動突部にてロックプレートの両側部の係合板部が押動され、このロックプレートの両側部の係合板部が嵌合体の嵌合突部の両側部の係合面部に沿って移動されるとともに、この両側部の係合板部の一端部間に設けられた圧着板部の先端部の圧着部が嵌合突部から離間する方向に向かって進出される。
【０００８】
そして、圧着板部の先端部の圧着部が取付孔の壁面に圧着され、この圧着板部の進出が阻止されるとともに、この圧着板部の先端部の圧着部を支えとして嵌合突部が圧着部の進出方向とは逆方向に移動され、この嵌合突部の圧着部とは反対側に位置する側面部が取付孔の壁面に圧着される。
【０００９】
したがって、扉体の取付孔内に嵌合体の嵌合突部を嵌合し、この嵌合体の当接板部にロックレバーを閉回動することにより、この嵌合体の嵌合突部から進出されて取付孔の壁面に圧着されるロックプレートの先端部の圧着部及びこの圧着部にて圧着部と反対側に移動されて取付孔の壁面に圧着される嵌合突部の圧着部とは反対側に位置する側面部にて嵌合体が扉体の取付孔に簡単にかつ確実に固定される。そして、扉体の取付孔から嵌合体がこの嵌合体の嵌合方向と反対側に抜け出すことを確実に防止される。
【００１０】
請求項２記載のヒンジ取付装置は、請求項１記載のヒンジ取付装置において、ロックプレートの係合板部は、ロックレバーの押動突部に押動されるとともにこの押動突部の押動を案内する傾斜した被押動部を有し、ロックレバーの押動突部は、前記被押動部にそれぞれ係合してこの被押動部を押動する押動傾斜部と、この押動傾斜部に連続して形成され被押動部にそれぞれ当接して取付孔の壁面に圧着部を圧着した状態にロックプレートの両側部の係合板部を保持する保持突部と、を有する、ものである。
【００１１】
そして、嵌合体の当接板部上に向かってロックレバーを閉回動することにより、このロックレバーの押動突部の押動傾斜部にてロックプレートの両側部の係合板部の傾斜した被押動部が押動され、このロックプレートの両側部の係合板部が嵌合体の嵌合突部の両側部の係合面部に沿って移動されるとともに、この両側部の係合板部の一端部間に設けられた圧着板部の先端部の圧着部が嵌合突部から離間する方向に向かって進出される。
【００１２】
また、圧着板部の先端部の圧着部が取付孔の壁面に圧着され、この圧着板部の進出が阻止されるとともに、この圧着板部の先端部の圧着部を支えとして嵌合突部が圧着部の進出方向とは逆方向に移動され、この嵌合突部の圧着部とは反対側に位置する側面部が取付孔の壁面に圧着されるとともに、このロックレバーの押動突部の押動傾斜部がロックプレートの両側部の係合板部の傾斜した被押動部から外れる。
【００１３】
そして、この傾斜した被押動部にはロックレバーの押動突部の保持突部が当接され、このロックレバーの保持突部にて互いに反対方向に向かって進出移動されたロックプレート及び嵌合突部を有する嵌合体がそれぞれ進出移動された状態に位置保持される。
【００１４】
したがって、扉体の取付孔内に嵌合体の嵌合突部を嵌合し、この嵌合体の当接板部にロックレバーを閉回動することにより、この嵌合体の嵌合突部から進出されて取付孔の壁面に圧着されるロックプレートの先端部の圧着部及びこの圧着部にて圧着部と反対側に移動されて取付孔の壁面に圧着される嵌合突部の圧着部とは反対側に位置する側面部にて嵌合体が扉体の取付孔に簡単にかつ確実に固定される。そして、扉体の取付孔から嵌合体がこの嵌合体の嵌合方向と反対側に抜け出すことを確実に防止される。
【００１５】
請求項３記載のヒンジ取付装置は、請求項１記載のヒンジ取付装置において、嵌合突部の両側部は、この係合面部に係合したロックプレートの両側部の係合板部を進出方向に案内するガイドを有する、ものである。
【００１６】
そして、嵌合体の当接板部上に向かってロックレバーが閉回動され、このロックレバーの押動突部にてロックプレートの両側部の係合板部が押動され、このロックプレートの両側部の係合板部が嵌合体の嵌合突部の両側部の係合面部に沿って移動されるときは、このロックプレートの両側部の係合板部がガイドにて案内されて移動され、この両側部の係合板部の一端部間に設けられた圧着板部の先端部の圧着部が嵌合突部から離間する方向に向かってスムーズに進出される。
【００１７】
請求項４記載のヒンジ取付装置は、請求項１記載のヒンジ取付装置において、嵌合体の嵌合突部は、ロックプレートの圧着部と反対側に位置する側面部に取付孔の壁面に圧着する圧着突部を有する、ものである。
【００１８】
そして、圧着板部の先端部の圧着部が取付孔の壁面に圧着され、この圧着板部の進出が阻止されるとともに、この圧着板部の先端部の圧着部を支えとして嵌合突部が圧着部の進出方向とは逆方向に移動され、この嵌合突部の圧着部とは反対側に位置する側面部の圧着突部が取付孔の壁面に圧着される。
【００１９】
したがって、扉体の取付孔内に嵌合体の嵌合突部を嵌合し、この嵌合体の当接板部にロックレバーを閉回動することにより、この嵌合体の嵌合突部から進出されて取付孔の壁面に圧着されるロックプレートの先端部の圧着部及びこの圧着部にて圧着部と反対側に移動されて取付孔の壁面に圧着される嵌合突部の圧着部とは反対側に位置する側面部の圧着突部にて嵌合体が扉体の取付孔に簡単にかつ確実に固定される。そして、扉体の取付孔から嵌合体がこの嵌合体の嵌合方向と反対側に抜け出すことを更に確実に防止される。
【００２０】
請求項５記載のヒンジ取付装置は、請求項１記載のヒンジ取付装置において、嵌合体の当接板部は、ロックレバーの押動突部を案内する案内長孔を有する、ものである。
【００２１】
そして、ロックレバーの閉回動時にはこのロックレバーの押動突部が嵌合体の当接板部の案内長孔に案内されてロックプレートを押動する方向に向かってスムーズに移動される。
【００２２】
請求項６記載のヒンジ取付装置は、請求項１記載のヒンジ取付装置において、嵌合体の当接板部は、扉体の取付孔の両側部に形成された位置決め孔内にそれぞれ嵌合する嵌合突起を有する、ものである。
【００２３】
そして、この両側部の位置決め孔内に当接板部の嵌合突起を嵌合することにより、取付孔内に嵌合した嵌合体が確実に回り止めされる。
【００２４】
【発明の実施の形態】
以下、本発明の一実施の形態を添付図面を参照して説明する。
【００２５】
１は家具本体に固定されるヒンジ基体で、このヒンジ基体１は前記家具本体に図示しない固定ベースを介して固定する固定具２を有している。また、前記ヒンジ基体１の一端部には重ね合わせた第１のリンクアーム３及び第２のリンクアーム４の基端部が支軸５，６にてそれぞれ回動自在に軸着され、この第１のリンクアーム３及び第２のリンクアーム４の先端部には前記家具本体に扉体７を開閉自在に取付ける取付手段８が略Ｕ字形状に形成されて支軸９にて回動自在に取り付けられている。
【００２６】
前記取付手段８は、前記扉体７の所定の位置に形成されて有底円形状の取付孔10内に嵌合する嵌合突部11を有するとともに前記取付孔10の開口縁部に当接する当接板部12を有する嵌合体13と、この嵌合体13にこの嵌合体13から離間する方向に進出可能に設けられ先端部に前記取付孔10の壁面14に圧着する圧着部15を有するロックプレート16と、前記嵌合体13の当接板部12に支軸17にて回動自在に設けられこの当接板部12上に閉回動時に前記ロックプレート16の圧着部15を前記取付孔10の壁面14に圧着させる方向にこのロックプレート16を押動する押動突部18を備えたロックレバー19と、を有して構成されている。
【００２７】
前記嵌合体13の嵌合突部11は、前記取付孔10の壁面14に対向する両側部に形成され前記ロックプレート16を係合する係合面部20と、この両側部の係合面部20間の前記ヒンジ基体１側の一端部に形成された一方側端板21と、前記両側部の係合面部20間の他端部すなわち前記圧着部15と反対側の他端部に外方に向かって突出して円弧状に彎曲して形成された他方側端板22と、を有して底面からみて略矩形状に形成されている。
【００２８】
また、前記両側部の係合面部20は、前記ヒンジ基体１の幅方向と同じ方向の両側部、すなわち、前記扉体７に取付け時では扉体７の上下に位置する両側部に形成され、その下端部に前記一方側端板21側に位置して前記ヒンジ基体１側に向かって平行に形成された前記ロックプレート16のガイドとしてのガイド溝23を有している。
【００２９】
また、前記他方側端板22は、その外周面下部に前記取付孔10の壁面14に圧着する複数の突起24を数段に亘って並設して突設された圧着突部25を有している。この圧着突部25は前記扉体７に取付け時では扉体７を正面からみて左右方向の一方側に位置して前記取付孔10の壁面14に圧着するようになっている。
【００３０】
さらに、前記両側部のガイド溝23の他端部側に位置して前記両側部の係合面部20は、その外面に突設され前記ロックプレート16の進出方向に対して交差する方向（係合面部20の幅方向）の係合突条26を有し、この係合突条26は、前記嵌合突部11の他方側端板22側に位置して前記係合面部20に向かって傾斜した係合面26a を有している。
【００３１】
前記嵌合体13の当接板部12は、前記両側部のガイド溝23上に離間位置して前記両側部の係合面部20の上端部にそれぞれ水平状に一体に形成され前記ロックプレート16のガイド兼用の両側部の円弧状フランジ部27と、この両側部の円弧状フランジ部27に一連に水平状に一体に形成され前記円弧状フランジ部27より外方に向かって両端部を突出した矩形状フランジ部28と、を有して形成されている。
【００３２】
また、前記矩形状フランジ部28は、両側部に前記ロックレバー19の両側部の押動突部18を案内する長溝状の案内長孔29を有するとともに、この両側部の案内長孔29の他端部より離間してこの矩形状フランジ部28の他端縁部の両側上部に前記支軸17を挿通して軸支した軸支部30を有している。
【００３３】
また、前記矩形状フランジ部28は、両端部の近傍に位置して裏面部に前記扉体７の取付孔10に近接した両側部、すなわち、扉体７の取り付け状態では取付孔10に近接した上下部に形成された位置決め孔31内にそれぞれ嵌合する筒状の嵌合突起32を有している。
【００３４】
そして、前記嵌合体13の嵌合突部11は前記当接板部12を開口縁部として上面を開口した嵌合凹部11a を有して形成され、この嵌合凹部11a 内にこの嵌合体13の回動時に前記第１のリンクアーム３及び第２のリンクアーム４が収容されるようになっている。
【００３５】
つぎに、前記ロックプレート16は、前記嵌合体13の嵌合突部11の両側部の係合面部20にそれぞれ進出可能に係合された両側部の係合板部33と、この両側部の係合板部33の一端部間に設けられ先端部に前記取付孔10の壁面14に圧着する前記圧着部15を形成した圧着板部34と、を有して平面視略Ｕ字形状に形成されている。
【００３６】
前記両側部の係合板部33は、前記円弧状フランジ部27と前記ガイド溝23との間に進退可能に配置される幅で前記嵌合突部11の両側部の係合面部20を挟持する弾性を有してそれぞれ細長板状に形成され、その長さ方向の略中間部にこのロックプレート16の進出時に前記嵌合突部11の両側部の係合面部20に突設された係合突条26の係合面26a に係合する小突起35をそれぞれ有している。
【００３７】
そして、前記ロックプレート16は、両側部の係合板部33が弾性により前記嵌合突部11の両係合面部20に係合して嵌合突部11に仮止めされ、このロックプレート16の進出時はこの両係合板部33の小突起35が両係合突条26の係合面26a に係合してこのロックプレート16の進出移動が阻止されるが、このときにロックプレート16の先端部の圧着部15が取付孔10の壁面14に圧着されるようになっている。また、両係合板部33の小突起35が両係合突条26の係合面26a に係合した状態で、このロックプレート16のロックが解除されるとともに、両係合板部33の弾性によりロックプレート16が仮止め位置に後退されるようになっている。
【００３８】
また、前記両側部の係合板部33は、前記圧着部15と反対側の他端部に前記ロックレバー19の押動突部18に押動されるとともにこの押動突部18の押動下降を案内する下方に向かって拡開傾斜した被押動部36をそれぞれ有している。
【００３９】
また、前記圧着部15を先端部に有する圧着板部34は、前記両側部が係合板部33の一端部間に一体に形成され、両側部に前記両側部のガイド溝23に進退可能に係合した係合片37をそれぞれ有するとともに、この両側部の係合片37の先端部に連続した圧着板部34の後端部に前記嵌合突部11の一方側端板21に当接する当接縁部38を有している。
【００４０】
さらに、前記圧着板部34は、前記両側部の係合片37の先端部から上方に向かって所定の傾斜角度に傾斜して形成され、この圧着板部34の先端部に形成された圧着部15は、凹凸を繰り返して略鋸刃状に形成された食込み突縁39にて円弧状に形成されている。前記圧着板部34の圧着部15（食込み突縁39）は、前記扉体７に取付け時では扉体７を正面からみて左右方向の他方側に位置して前記取付孔10の壁面14に圧着するようになっている。
【００４１】
そして、前記ロックプレート16の両側部の係合板部33を前記嵌合突部11の両側部の係合面部20に押し込んで嵌合することにより、この両側部の係合板部33が両側部の係合面部20にこの係合面部20を弾性により挟持する状態で嵌合され、その圧着板部34の後端部の当接縁部38が前記嵌合突部11の一方側端板21に当接され、かつ、この両側部の係合板部33の小突起35が前記両側部の係合面部20の係合突条26に係合されるとともに、この両側部の係合面部20のガイド溝23にロックプレート16の両側部の係合片37が係合される。
【００４２】
したがって、嵌合突部11にロックプレート16を押し込んで嵌合することにより、嵌合突部11にロックプレート16が簡単に組み付けられるとともに、両側部の係合板部33及びこの係合板部33の小突起35にて嵌合突部11にロックプレート16が仮止めされる。
【００４３】
つぎに、前記ロックレバー19は、前記嵌合凹部11a の上面を開口形成した凹窪部28a を有する前記当接板部12の矩形状フランジ部28と略同形状に形成され、その中間部に前記凹窪部28a と略同形状の凹窪部19a を有し、この凹窪部19a の両側縁部に近接位置してこのロックレバー19の裏面部に前記押動突部18がそれぞれ下方に向かって一体に突設されている。
【００４４】
前記両側部の押動突部18は、前記ロックプレート16の両側部の係合板部33の板厚よりも厚い板厚でかつ前記両側部の案内長孔29に進退自在に挿通可能な押動突片40にてそれぞれ形成されている。
【００４５】
前記両側部の押動突片40は、下端部に前記被押動部36にそれぞれ係合してこの被押動部36を押動する円弧状の押動傾斜部41と、この押動傾斜部41に連続して形成され被押動部36にそれぞれ当接して前記取付孔10の壁面14に前記ロックプレート16の圧着部15（食込み突縁39）を圧着した状態にこのロックプレート16の両側部の係合板部33を保持する保持突部42と、を有し、前記押動傾斜部41は、前記被押動部36に係合する円弧状の係合溝43を有して形成されている。
【００４６】
また、前記ロックレバー19は、両端部に前記支軸17を挿通した挿通孔44を有する軸支部45をそれぞれ有し、この両端部の軸支部45を介して前記支軸17を中心に前記当接板部12の矩形状フランジ部28上に対して開閉回動されるようになっている。そして、このロックレバー19は常時は矩形状フランジ部28上に離間して開回動した状態になっている。
【００４７】
なお、46は前記ヒンジ基体１を調整する調整ねじ、47は前記ヒンジ基体１を固定する固定ねじである。また、前記扉体７の取付孔10は扉体７の大きさにもよるが少なくとも扉体７の上下部の裏面にそれぞれ開口して形成され、これらの取付孔10の両側の前記位置決め孔31は扉体７の裏面にそれぞれ開口して形成されている。前記各取付孔10及び前記各位置決め孔31は扉体７を構成する一工程として工場で形成することにより、扉体７の梱包、搬送及び現場作業が容易になる。
【００４８】
つぎに、前記実施の形態の作用を説明する。
【００４９】
まず、嵌合体13の嵌合突部11にロックプレート16を組み付けるときは、ロックプレート16の両側部の係合板部33を嵌合突部11の両側部の係合面部20に押し込んで嵌合することにより、この両側部の係合板部33が両側部の係合面部20にこの係合面部20を弾性により挟持する状態で係合され、その圧着板部34の後端部の当接縁部38が前記嵌合突部11の一方側端板21に当接され、かつ、この両側部の係合板部33の小突起35が両側部の係合面部20の係合突条26の係合面26a から離間されるとともに、この両側部の係合面部20のガイド溝23にロックプレート16の両側部の係合片37が係合される。
【００５０】
このとき、ロックプレート16は両側部の係合板部33及び圧着板部34を有して平面視略Ｕ字形状に形成されているため、両側部の係合板部33の被押動部36間から嵌合突部11の両側部の係合面部20に押し込んで嵌合することにより、嵌合突部11の両側部の係合面部20にロックプレート16が簡単に組み付けられるとともに、両側部の係合板部33及びこの係合板部33の小突起35にて嵌合突部11にロックプレート16が仮止めされる。
【００５１】
また、嵌合体13の矩形状フランジ部28の両側の軸支部30にロックレバー19の両側の軸支部45を位置合わせした状態でロックレバー19の両端部に開口した挿通孔44から矩形状フランジ部28の両側の軸支部30に支軸17を挿通することにより、矩形状フランジ部28の両側の軸支部30に支軸17を介してロックレバー19が簡単に開閉回動自在に組み付けられる。
【００５２】
したがって、ヒンジ基体１の取付手段８は、嵌合体13と、ロックプレート16と、ロックレバー19と、を有して構成されているため、これらの部品点数が少なく構成が簡単であり、これらを組付ける組付け操作が容易なものである。
【００５３】
つぎに、扉体７にヒンジ基体１を取り付けるときは、扉体７の側縁部7aに対してヒンジ基体１を交差する状態で、この扉体７の取付孔10内に嵌合体13の嵌合突部11を嵌合するとともに、この嵌合体13の両側部の嵌合突起32を取付孔10の両側部の位置決め孔31内に嵌合することにより、この嵌合体13の当接板部12が取付孔10及び位置決め孔31の開口縁部に当接される。このとき、ロックレバー19は嵌合体13の当接板部12から開回動されて開いた状態になっている。
【００５４】
また、嵌合体13の当接板部12上に向かって支軸17を中心としてロックレバー19を閉回動することにより、このロックレバー19の両側部の押動突部18すなわち押動突片40が矩形状フランジ部28の両側部の案内長孔29に案内されて下降され、この両側部の押動突片40の押動傾斜部41にてロックプレート16の両側部の係合板部33の傾斜した被押動部36がそれぞれ押動される。
【００５５】
そして、このロックプレート16の両側部の係合板部33が嵌合体13の嵌合突部11の両側部の係合面部20に沿って移動されるが、このとき、両側部の係合板部33の一端部間に一体の圧着板部34の両側部の係合片37が両側部の係合面部20のガイド溝23に案内されて移動され、かつ、このガイド溝23に対向した円弧状フランジ部27に沿って移動されることにより、このロックプレート16は両側部の係合板部33の一端部間に一体の圧着板部34の先端部の圧着部15すなわち食込み突縁39が嵌合突部11から離間する方向に向かってスムーズに進出される。
【００５６】
また、ロックプレート16は両側部の係合板部33は、ガイド溝23とこのガイド溝23に対向する円弧状フランジ部27との間に位置してこれらに案内されて進出されるため、このロックプレート16は両側部の係合板部33の進出時にこのロックプレート16が傾くことなくスムーズに進出される。
【００５７】
また、ロックプレート16が進出されることにより、このロックプレート16の圧着板部34の先端部の圧着部15すなわち食込み突縁39が取付孔10の壁面14に圧入されて食込んで圧着され、この圧着板部34の進出が阻止されるとともに、この圧着板部34の先端部の圧着部15すなわち食込み突縁39を支えとして嵌合突部11が圧着部15の進出方向とは逆方向に移動される。
【００５８】
そして、この嵌合突部11の圧着板部34の圧着部15とは反対側に位置する他方側端板22の多数の突起24にて形成された圧着突部25が取付孔10の壁面14に圧入されて食込んで圧着されるとともに、このロックレバー19の押動突片40の押動傾斜部41がロックプレート16の両側部の係合板部33の傾斜した被押動部36から押動突片40の押し込み方向に向かって突出して外れる。
【００５９】
また、押動傾斜部41がロックプレート16の係合板部33の傾斜した被押動部36から外れると、この傾斜した被押動部36にはロックレバー19の押動突片40の保持突部42が当接され、このロックレバー19の保持突部42にて互いに反対方向に向かって進出移動されたロックプレート16及び嵌合突部11を有する嵌合体13がそれぞれ進出移動された状態に位置保持される。
【００６０】
