Description

【０００１】
【発明の属する技術分野】
本発明は、不使用時に使用位置から格納位置に回動して格納される格納式アシストグリップに関し、特に、その回動を安定して行わせるための対策に関する技術分野に属する。
【０００２】
【従来の技術】
従来より、この種の格納式アシストグリップとして、車体パネル等の固定体に固定される１対の取付座と、これら取付座にそれぞれ脚部にて回動可能に軸支された長尺状のグリップ本体と、このグリップ本体を使用位置から格納位置に回動付勢するコイルばね等の付勢手段とを備えたものが知られている。
【０００３】
そして、例えば特開２００１―５８５３５号公報に示されるように、高粘度の粘性剤が封入されたダンパ手段をグリップ本体と取付座との間に一体的に組み込んだものが提案されている。
【０００４】
この提案のものでは、長さ方向両端部の脚部でそれぞれ取付座に回動可能に軸支されたグリップ本体に対し、その各脚部に、グリップ本体が格納位置にある状態で取付座の一部を収容する収容部を形成し、ダンパ手段を設ける側の取付座に、グリップ本体の長さ方向を中心軸とする有底円形状の凹部と、この凹部の底面に突設された嵌入軸とを有する筒状部を形成し、その凹部内に回動可能に嵌入されかつ嵌入軸を嵌入させる嵌入部を有するスペーサを、収容部のグリップ本体長さ方向に対向する２つの側壁のうちの凹部開放側の側壁に係合する一方、凹部の底部側の筒状部に収容部の他方の側壁を相対回動に支承し、このスペーサの外周面と凹部の内周面との間、及び嵌入軸の外周面と嵌入部の内周面との間に粘性剤を介在させ、この粘性剤の粘性によりスペーサつまりグリップ本体の回動に抵抗を生じさせるようにしている。
【０００５】
一方、ＥＰ特許公開公報０８７５４２０Ａ２には、一方の取付座に、底部側に向かって小径となるテーパ状の凹部を形成し、この凹部内に先細りテーパ状のスペーサを先端側から挿入して、このスペーサの中心孔に支持軸を挿通してキーにより回転一体に係合し、この支持軸の両端部をグリップ本体の脚部に回転一体に取付固定するとともに、凹部のテーパ状内周面とスペーサのテーパ状外周面との間の隙間に粘性剤を充填して封入し、グリップ本体が支持軸回りに回動するときに、スペーサと凹部との間の粘性剤の粘性によりスペーサつまりグリップ本体の回動に抵抗を生じさせるようにしたダンパ手段を備えたものが提案されている。
【０００６】
【発明が解決しようとする課題】
ところで、上記グリップ本体を樹脂製のものとし、この樹脂製のグリップ本体を成形によって製造することが一般的に行われる。しかし、その場合、樹脂の成形時の収縮等に伴ってグリップ本体がある程度変形することは避けられず、このグリップ本体が長尺状のものであるが故に、グリップ本体の両脚部の軸心をいずれも同時にそれぞれ対応する取付座の支持部の軸心と正確に一致させることが難しく、いずれか一方の側でずれることがある。このずれが生じると、グリップ本体の回動がスムーズに行われずに、付勢手段の回動付勢力があっても使用位置から格納位置に戻らなかったり、或いは粘性剤の密封が不十分になって漏出したりする等の問題を招来することになる。
【０００７】
本発明は斯かる点に鑑みてなされたもので、その目的は、上記の如き格納式アシストグリップにおけるグリップ本体の脚部と取付座との間に設けられるダンパ手段の構造を改良することにより、樹脂製のグリップ本体に成形による多少の変形が生じていても、その影響を受けることなく、グリップ本体をスムーズに回動させ、粘性剤の漏出を防止して、格納式アシストグリップの信頼性や作動安定性の向上を図ることにある。
【０００８】
【課題を解決するための手段】
上記の目的を達成すべく、この発明では、グリップ本体の脚部側に基端部で固定されかつ取付座の凹部に粘性剤充填用の隙間を区画するように回動可能に嵌入されるスペーサを有底中空状のものとし、その基端部のみがグリップ本体の脚部に固定されるようにして、スペーサの支持構造を片持ち構造とした。
【０００９】
具体的には、請求項１の発明では、固定体に固定される１対の取付座と、これら取付座にそれぞれ脚部にて回動可能に軸支された長尺状の樹脂製のグリップ本体と、このグリップ本体を使用位置から格納位置に回動付勢する付勢手段とを備えた格納式アシストグリップが前提である。
【００１０】
そして、その特徴とする特定事項は以下のとおりである。すなわち、上記脚部のうち上記グリップ本体が格納位置にあるときの上記固定体との対向面には、グリップ本体の長さ方向に対向する２つの側壁を有しかつ該グリップ本体の格納位置で上記取付座の一部を収容する収容部が切り欠いて形成されている。
【００１１】
また、上記１対の取付座のうちの少なくとも一方には、グリップ本体の長さ方向に延びる有底筒状の凹部を有する支持部が形成されていて、この凹部の開放口は上記収容部の２つの側壁のうちの一方の側壁側に、また底部は他方の側壁側にそれぞれ位置している。
【００１２】
さらに、上記収容部の２つの側壁のうち上記凹部の開放口に面する一方の側壁には係止口部が凹部と同心状に貫通形成されている。
【００１３】
そして、上記支持部の凹部には、先端部を凹部の底部側に位置させかつ基端部を上記収容部の側壁の係止口部に挿通して回動不能に係止せしめた樹脂製のスペーサが上記先端部を自由端として回動可能に嵌入されている。
【００１４】
このスペーサは、上記先端部が底壁部とされ基端部に開口を有する有底の中空筒状体からなっていて、該スペーサの少なくとも凹部内に位置する部分の肉厚が略均等に設けられている。
【００１５】
また、上記凹部の内周面とスペーサの外周面との間の隙間、及びスペーサの先端部と凹部の底部との間の隙間に粘性剤が充填されている。
【００１６】
さらに、上記凹部の開放口とスペーサとの間に上記隙間からの粘性剤の流出を阻止するシール材が介在されている。
【００１７】
上記の構成によると、固定体に固定される１対の取付座にそれぞれグリップ本体が脚部にて回動可能に軸支され、このグリップ本体は付勢手段により使用位置から格納位置に回動付勢される。また、１対の取付座のうちの少なくとも一方に、凹部を有する支持部が設けられている一方、この取付座に対応するグリップ本体の脚部には、凹部内に回動可能に嵌入される樹脂製のスペーサがその基端部を脚部における収容部の側壁の係止口部に挿通されて回動不能に係止され、この凹部の内周面とスペーサの外周面との間の隙間、及びスペーサの先端部と凹部の底部との間の隙間に粘性剤がシール材で封止された状態で介在されているので、この粘性剤の粘性によりダンパ作用が得られ、上記付勢手段によりグリップ本体が使用位置から格納位置へ回動するときに、そのグリップ本体の回動に抵抗が生じて、グリップ本体がゆっくりと回動するようになり、その動きに高級感が得られる。また、上記グリップ本体の格納位置では、その脚部の収容部内に取付座の一部が収容される。
【００１８】
そのとき、上記グリップ本体の脚部における収容部の側壁の係止口部に回動不能に係止された樹脂製スペーサは、取付座における支持部の凹部内にスペーサ先端部を自由端として回動可能に嵌入され、その基端部のみがグリップ本体の脚部に係止固定されているので、このスペーサの支持構造が片持ち状態となり、樹脂製のグリップ本体が成形時の収縮等に伴って変形し、その両脚部の軸心がそれぞれ対応する取付座の支持部の軸心に対しずれていても、そのずれを上記片持ち状態のスペーサの先端側自由端の相対変位によって吸収することができる。このことで、グリップ本体の回動をスムーズに行って、グリップ本体を使用位置から格納位置に確実に戻すことができるとともに、取付座の凹部にスペーサを両者間の隙間に粘性剤の密封性よく封入して、粘性剤が漏出するのを防止することができる。
【００１９】
また、上記スペーサは、凹部の底部側に位置する先端部が底壁部とされた中空筒状体からなっているので、スペーサの樹脂使用量を減らしてコストを下げることができる。しかも、スペーサの少なくとも凹部内に位置する部分の肉厚が略均等であるので、その樹脂製のスペーサを成形したときに変形が生じたとしても、その変形を均一にすることができ、よって上記スペーサの片持ち支持構造による効果、つまりスペーサの回動のスムーズ化や粘性剤の漏出防止をさらに確実に行うことができる。
【００２０】
請求項２の発明では、上記スペーサの先端部外面又は凹部の底部内面の一方には、スペーサ又は凹部と同心状に突出するピボット部が形成されている一方、スペーサの先端部外面又は凹部の底部内面の他方には、スペーサの先端側が揺動可能となるように上記ピボット部を当接させるピボット当接部が形成されていることを特徴とする。
【００２１】
この構成によれば、スペーサ先端部の自由端が凹部の底部内面に対し、ピボット部とピボット当接部との当接により揺動可能に支持されることとなり、自由端であるスペーサの先端部を、スペーサの片持ち構造の機能を阻害することなく凹部の底部内面に安定して支持することができ、スペーサの回動のスムーズ化や粘性剤の漏出防止をより一層確実に行うことができる。
【００２２】
請求項３の発明では、上記請求項２の格納式アシストグリップにおいて、上記スペーサの底壁部は、ピボット部がピボット当接部との当接状態でスペーサ中心線方向に沿って変形可能となるように弾性を有することを特徴とする。
【００２３】
このことで、製造誤差等により、スペーサの長さが凹部の深さよりも大きくなっていたとしても、その差を、スペーサの底壁部がピボット部とピボット当接部との当接状態で弾性変形することで吸収でき、スペーサの基端部をグリップ本体の脚部における収容部の側壁の係止口部に確実に係止することができ、スペーサの凹部への嵌入も容易に行われる。
【００２４】
【発明の実施の形態】
（実施形態１）
図５は本発明の実施形態１に係る回動型の格納式アシストグリップＧを示し、このアシストグリップＧは、例えば車両における車室の側壁に車室内に臨むように取付固定される。
【００２５】
上記アシストグリップＧは、例えばＰＰ（ポリプロピレン樹脂）等からなる樹脂製のグリップ本体１と、例えばＰＯＭ（ポリアセタール）等からなる第１及び第２の１対の取付座１１，１２とを備えてなる。上記グリップ本体１は長尺バー状のもので、その長さ方向が車体の前後方向と略一致するように配置されている。このグリップ本体１は長さ方向両端部が同じ方向に湾曲されて略コ字状をなし、その長さ方向両端部がそれぞれ第１及び第２脚部１ａ，１ｂとされている。
【００２６】
一方、図３及び図４に示すように、各取付座１１，１２は車室の側壁の一部を構成する取付体としての車体パネルＰに表面側（車室側）から取付固定されている。この各取付座１１，１２の取付位置に対応する車体パネルＰにはボルト挿通孔Ｐ１が貫通形成され、車体パネルＰの裏面（背面）には上記ボルト挿通孔Ｐ１に対応してナットＮ（ウェルドナット）が溶接固定されている。
【００２７】
そして、上記グリップ本体１は、その両脚部１ａ，１ｂにてそれぞれ取付座１１，１２に対し回動可能に軸支されており、このような両脚部１ａ，１ｂでの軸支構造により、グリップ本体１は使用位置及び格納位置の間で回動し、使用位置にあるときには、図１、図３〜図５に示すようにグリップ本体１の中間部が車室内方に突出して水平面からやや斜め下方に向いた状態となる一方、格納位置にあるときには、図２に示すように、グリップ本体１が上記使用位置から略９０°上向きに回動して車室側壁（車体パネルＰ）に沿った状態となる。
【００２８】
上記グリップ本体１の各脚部１ａ，１ｂにおいて、グリップ本体１が格納位置にあるときの車室側壁の車体パネルＰに対向する外面には、断面略矩形状に切り欠いてなる略半楕円形状の凹部からなる収容部２が形成されている。この各収容部２の周りには、グリップ本体１の長さ方向に対向する内外側壁２ａ，２ｂと、この内外側壁２ａ，２ｂの対向方向に直交する方向に対向し、脚部１ａの基部側及び先端側に位置する基部側及び先端側壁２ｃ，２ｄとが設けられ、内外側壁２ａ，２ｂ及び基部側壁２ｃは互いに略同じ高さであるが、先端側壁２ｄは、他の側壁２ａ〜２ｃに比べて低く形成されている。そして、グリップ本体１の格納位置で各収容部２内に取付座１１，１２の一部（取付座本体１３の先端部）を収容するようになっている。
【００２９】
上記グリップ本体１の第１脚部１ａ（図５において右側のもの）と、この第１脚部１ａに対応する第１取付座１１との間には、図４に示すように、グリップ本体１を使用位置から格納位置に向かうように回動付勢する付勢手段としての捩りコイルばね７が、また第２脚部１ｂ（図５において左側のもの）と、この第２脚部１ｂに対応する第２取付座１２との間には、図１〜図３に示すように、グリップ本体１の回動に抵抗を付与するダンパ手段２４がそれぞれ設けられている。
【００３０】
上記第１及び第２取付座１１，１２はその大半が互いに同じ構造で、一部分のみの構造が異なる。この両取付座１１，１２の同じ構造の部分について説明すると、図１〜図４に示す如く、各取付座１１，１２は、車室側に開口する有底箱状の取付座本体１３を備えている。この箱状の取付座本体１３の平面視は、上記収容部２に対応する形状、つまり楕円（長円）を長径方向に２分割した略半楕円形状で、その開口周縁部には取付座本体１３の開口を閉じるためのリッド１４が薄肉ヒンジ１４ａにより一体に形成されている。取付座本体１３の底壁部にはボルト挿通孔１５が貫通形成されており、このボルト挿通孔１５を車体パネルＰのボルト挿通孔Ｐ１に一致させ、両ボルト挿通孔１５，Ｐ１に取付ボルトＢを挿通して、その先端部を車体パネルＰ裏面の上記ウェルドナットＮに螺合締結することにより、各取付座１１，１２が車体パネルＰに取付固定されている。
【００３１】
尚、１３ａは取付座本体１３の底部周りに突設されたフランジで、このフランジ１３ａは、車体パネルＰ表側のトリム材（図示せず）上にそれを覆うように配置される。
【００３２】
上記両取付座１１，１２の異なる部分の構造について説明すると、図４に示すように、上記捩りコイルばね７側の第１取付座１１において、その取付座本体１３の側壁のうち格納位置にあるグリップ本体１の脚部１ａ先端側に位置する側壁の開口側端部には、グリップ本体１の長さ方向に延びる中空円筒状の支持部１７が一体に形成され、この支持部１７の周壁には矩形状の開口１８が形成され、支持部１７の長さ方向両端壁部にはそれぞれ軸挿通孔１９，１９（１つのみ図示する）が同心状に設けられている。そして、支持部１７の両軸挿通孔１９，１９に支持軸８を挿通し、この支持軸８の両端部をそれぞれ上記グリップ本体１の第１脚部１ａにおける収容部２の内外側壁２ａ，２ｂに形成した軸支持穴（図示せず）に嵌入することで、グリップ本体１の第１脚部１ａを第１取付座１１に支持軸８を介して回動可能に支持するようにしている。
【００３３】
また、グリップ本体１の第１脚部１ａにおける収容部２の先端側壁２ｄにはばね受部３が、また取付座１１の支持部１７内面の一部にもばね受部２０がそれぞれ切り欠いて形成されている。そして、上記捩りコイルばね７は上記支持部１７内に支持軸８の周りに配置された状態で収容され、この捩りコイルばね７の一端部は上記第１脚部１ａにおけるばね受部３に、また他端部は第１取付座１１の支持部１７におけるばね受部２０にそれぞれ係合されており、この捩りコイルばね７のばね力によりグリップ本体１を使用位置から格納位置に向かう方向（図４で反時計回り方向）に回動付勢している。
【００３４】
一方、図１〜図３に示すように、上記ダンパ手段２４側の第２取付座１２において、その取付座本体１３の側壁のうち格納位置にあるグリップ本体１の脚部１ａ先端側に位置する側壁の開口側端部には、グリップ本体１の長さ方向に延びる有底円筒状の支持部２６が一体に形成され、この支持部２６はその内部に底部側に向かって小径となる略テーパ状の凹部２８を有し、この凹部２８の開放口は上記グリップ本体１の第２脚部１ｂにおける収容部２の内外側壁２ａ，２ｂのうちの外側壁２ｂ側に、また底部は内側壁２ａ側にそれぞれ位置している。また、この支持部２６の外底面（凹部２８と反対側の面）には軸部２７が凹部２８と同心状に一体に突設されている。尚、２７ａは軸部２７の先端面に設けられたひけ防止用穴で、成形時の軸部２７のひけを防止するためのものである。
【００３５】
そして、上記グリップ本体１の第２脚部１ｂには、その収容部２の内外２つの側壁２ａ，２ｂのうち上記第２取付座１２における支持部２６の凹部２８の開放口に面する外側壁２ｂに略半楕円形状（他の形状でもよい）の係止口部４が凹部２８と同心状に貫通形成されている。一方、内側壁２ａには軸支持穴５が係止口部４（凹部２８）と同心状に形成されており、この軸支持穴５に上記支持部２６の軸部２７が回動可能に嵌入されている。尚、上記とは逆に、内側壁２ａに係止口部を、また外側壁２ｂに軸支持穴をそれぞれ設けてもよい。
【００３６】
さらに、上記支持部２６の凹部２８には例えばＰＯＭ等からなる樹脂製のスペーサ３１がその先端側から外周面と凹部２８の内周面との間、及びスペーサ３１先端部と凹部２８の底部との間にそれぞれ略一定の隙間Ｓ１，Ｓ２をあけた状態で回動可能に嵌入されている。このスペーサ３１は凹部２８に対し、上記第２脚部１ｂにおける収容部２の外側壁２ｂの外側から該外側壁２ｂの係止口部４を挿通して嵌入され、そのスペーサ３１の基端部外周面の断面形状は上記係止口部４と同じ形状に形成されていて、スペーサ３１の基端部は係止口部４に回動不能（回動一体）に係止されており、このことで、スペーサ３１は凹部２８の底部側に位置する先端部を自由端として回動可能に凹部２８に嵌入されている。
【００３７】
上記スペーサ３１は、その凹部２８の底部側に位置する先端部が底壁部とされかつ基端部に開口を有する有底中空筒状体からなり、このスペーサ３１の凹部２８内に位置する部分の肉厚は略均等に設けられている。また、スペーサ３１の基端部における開放口の周縁部には該開口を開閉するリッド３２が薄肉ヒンジ３３を介して回動可能に一体形成され、このリッド３２の先端部には係合突起３２ａが形成されている一方、スペーサ３１の基端部の一部には上記リッド３２先端部の係合突起３２ａに係合可能な係合孔３７が設けられており、リッド３２の係合突起３２ａをスペーサ３１基端部の係合孔３７に係合させることで、リッド３２を閉じ状態に保持する。
【００３８】
上記スペーサ３１の基端部には例えば４つの矩形状の開口３４，３４，…が周方向に間隔をあけて形成され、この開口３４を除いた部分は凹部２８内に嵌入された部分よりも若干薄肉の薄肉部３５とされていて、その外周面にはそれぞれ係止突起３６が設けられており、スペーサ３１を先端側から第２取付座１２の凹部２８内に嵌入して、その基端部の薄肉部３５を係止突起３６と共に外側壁２ｂの係止口部４を潜らせて撓み変形させながら、その係止突起３６を外側壁２ｂの内側に位置付けることにより、スペーサ３１の基端部を係止口部４に回動不能（回動一体）に係止するようになっている。尚、このスペーサ３１の基端部の係止口部４への係止状態ではリッド３２が薄肉ヒンジ３３回りに回動して開閉される。
【００３９】
そして、上記スペーサ３１の先端部（底壁部）外面には、その底壁部外面をテーパ面の断面が中凹状の円弧面になるようにテーパ状に突出させることでスペーサ３１と同心状に突出するピボット部３９が形成されている。また、スペーサ３１の肉厚が略均等になるように、スペーサ３１内部の底面は底壁部外面のピボット部３９に対応してテーパ形状に形成されている。
【００４０】
一方、凹部２８の底部内面は、スペーサ３１の先端部（底壁部）外面と対応するように中心部が部分的に凹陥され、この凹陥部分の中心部には、スペーサ３１の先端側が揺動可能となるように上記ピボット部３９を当接させるピボット当接部４２が形成されている。このピボット当接部４２は、スペーサ３１において係止口部４に係止固定された基端部を略中心とする円弧面からなっており、ピボット当接部４２でピボット部３９を摺接させることで、スペーサ３１の先端側を凹部２８内で揺動可能としている。
【００４１】
さらに、上記第２取付座１２の支持部２６における凹部２８の内周面と、この凹部２８内に嵌入されたスペーサ３１の外周面との間のテーパ状の隙間Ｓ１、及びこの隙間Ｓ１に連通する、スペーサ３１の先端部と凹部２８の底部との間の隙間Ｓ２にはそれぞれ例えばシリコン等の高粘度（１０００００ｃｐｓ以上が望ましい）の液体からなる粘性剤Ｌが充填されている。
【００４２】
また、上記凹部２８の開放口とスペーサ３１との間に上記隙間Ｓ１，Ｓ２からの粘性剤Ｌの流出を阻止するＯリング等からなるシール材４５が介在されている。具体的には、上記スペーサ３１の外周面において上記凹部２８の開放口近くの内周面に対応する部分にはシール溝４６がスペーサ３１の全周に亘って形成され、このシール溝４６に上記シール材４５が嵌装されている。このシール材４５の外周面は凹部２８の開放口近くの内周面にあるシール面４７に圧接しており、このシール材４５のシール面４７との圧接により、上記第２取付座１２の支持部２６における凹部２８の内周面とスペーサ３１の外周面との間の隙間Ｓ１、及びスペーサ３１の先端部と凹部２８の底部との間の隙間Ｓ２を封止して、それら隙間Ｓ１，Ｓ２からの粘性剤Ｌの流出を阻止するようにしている。
【００４３】
そして、以上の第２取付座１２の支持部２６における凹部２８の内周面とスペーサ３１の外周面との間の隙間Ｓ２、及びスペーサ３１の先端部と凹部２８の底部との間の隙間Ｓ２にそれぞれ充填されている粘性剤Ｌにより、グリップ本体１が回動するときの回動抵抗となるトルクを発生するダンパ手段２４が形成されている。
【００４４】
上記実施形態のアシストグリップＧをグリップ本体１の第２脚部１ｂにおいて車体パネルＰに組み付ける作業について説明すると、図６に示すように、予め、スペーサ３１外周のシール溝４６にシール材４５を嵌装するとともに、第２取付座１２の凹部２８内に開放口から必要量の粘性剤Ｌを充填しておく。このときの粘性剤Ｌの充填量（必要量）は、スペーサ３１の外周面と凹部２８の内周面との間の隙間Ｓ１の容積、及びスペーサ３１の先端部と凹部２８の底部との間の隙間Ｓ２の容積を合わせた合計よりも若干多めに設定する。こうすると、スペーサ３１を凹部２８内に嵌入して第２取付座１２に組み付けたときに、両隙間Ｓ１，Ｓ２から粘性剤Ｌが少し漏れ出る程度になり、エア抜きを行いながら各隙間Ｓ１，Ｓ２に粘性剤Ｌが充填される。
【００４５】
そして、まず、第２取付座１２の軸部２７の先端部をグリップ本体１の第２脚部１ｂにおける収容部２の内側壁２ａの軸支持穴５に嵌挿し、次いで、その収容部２の外側壁２ｂにおける係止口部４に上記スペーサ３１を先端側から挿通して、それを第２取付座１２の凹部２８内に開放口から嵌入し、このスペーサ３１の基端部を係止口部４に係止固定する。そして、このスペーサ３１が第２取付座１２の凹部２８内に適正位置まで完全に嵌入されたときに、上記シール材４５の外周部が凹部２８の開放口近傍内周面のシール面４７に圧接して、このシール面４７とスペーサ３１外周面との間の隙間が相対回転可能に気密状に閉塞され、上記スペーサ３１の外周面と凹部２８の内周面との間の隙間Ｓ１、及びスペーサ３１の先端部と凹部２８の底部との間の隙間Ｓ２にそれぞれ上記粘性剤Ｌが封入される。
【００４６】
このようにして第２取付座１２が組み付けられたアシストグリップＧは、第２取付座１２における取付座本体１３のボルト挿通孔１５に取付ボルトＢを挿通して第２取付座１２を車体パネルＰ裏面のナットＮに締結することにより、その第２取付座１２を介して車体パネルＰに組み付けられる。その後、第２取付座１２のヒンジ式のリッド１４を閉じることで、取付ボルトＢを覆って隠す。
【００４７】
一方、第１取付座１１においても、グリップ本体１の第１脚部１ａが支持軸８により回動可能に支持されるとともに、捩りコイルばね７が装着される。その後、第１取付座１１は上記第２取付座１２と略一緒にかつ同様にして車体パネルＰに組み付けられる。
【００４８】
したがって、この実施形態のアシストグリップＧにおいては、通常はグリップ本体１が捩りコイルばね７の付勢力により回動付勢されて格納位置に位置付けられており、このグリップ本体１の格納位置では、その各脚部１ａ，１ｂの収容部２内にそれぞれ取付座１１，１２の一部が収容されている。そして、車両の乗員がアシストグリップＧを使用するとき、そのグリップ本体１を手で掴んで捩りコイルばね７の付勢力に抗して使用位置に回動させればよい。また、このアシストグリップＧの使用停止時には、乗員がグリップ本体１から手を離すと、そのグリップ本体１は捩りコイルばね７の付勢力により取付座１１，１２に対し使用位置から格納位置へ回動しながら戻る。
【００４９】
このようなグリップ本体１の使用位置から格納位置への回動時（上記格納位置から使用位置への回動時にも同様のことが生じる）、グリップ本体１の第２脚部１ｂにおける収容部２の内側壁２ａが第２取付座１２の軸部２７回りに、またこの収容部２の外側壁２ｂに回動不能に係止されているスペーサ３１が第２取付座１２における支持部２６の凹部２８内でそれぞれ回動するが、上記スペーサ３１の外周面と凹部２８の内周面との間の隙間Ｓ１、及びスペーサ３１の先端部と凹部２８の底部との間の隙間Ｓ２にそれぞれ粘性剤Ｌが充填されているので、この粘性剤Ｌの粘性により上記スペーサ３１及びそれと一体化されているグリップ本体１の回動に抵抗（トルク）が生じる。このことで、グリップ本体１がゆっくりと使用位置から格納位置へ回動することとなり、グリップ本体１が車体パネルＰに強く当たることによる叩き音を発生させることがなく、その動きに高級感が得られる。
【００５０】
そのとき、上記グリップ本体１の第２脚部１ｂにおける収容部２の外側壁２ｂの係止口部４に基端部にて回動不能に係止されている樹脂製スペーサ３１は、第２取付座１２における支持部２６の凹部２８内にスペーサ３１先端部を自由端として回動可能に嵌入され、その基端部のみが第２脚部１ｂの収容部２の外側壁２ｂに固定されて、スペーサ３１の支持構造が片持ち構造となっている。このため、樹脂製のグリップ本体１が成形時の収縮等に伴い変形していて、その両脚部１ａ，１ｂの軸心がそれぞれ対応する取付座１１，１２の支持部１７，２６の軸心とずれていたとしても、そのずれを上記片持ち状態のスペーサ３１の先端側自由端の相対変位によって吸収することができる。その結果、グリップ本体１の回動をスムーズに行うことができ、グリップ本体１を捩りコイルばね７の付勢力によって使用位置から格納位置に確実に戻すことができる。しかも、上記軸心のずれの吸収により、スペーサ３１側のシール材４５を凹部２８内周面のシール面４７に有効に圧接させて、第２取付座１２の凹部２８とスペーサ３１との間の隙間Ｓ１，Ｓ２に粘性剤Ｌを確実に封入でき、粘性剤Ｌの漏出を防止することができる。これらにより、格納式アシストグリップＧの信頼性や作動安定性の向上を図ることができる。
【００５１】
また、上記スペーサ３１の先端部外面にピボット部３９が突設され、このスペーサ３１先端部外面に対向する凹部２８底部内面の中心部にはピボット部３９を当接させるピボット当接部４２が形成されて、これらピボット部３９とピボット当接部４２との当接によりスペーサ３１の先端側が揺動可能となっているので、スペーサ３１先端部の自由端を凹部２８の底部内面にピボット部３９とピボット当接部４２との当接により揺動可能に支持することができ、スペーサ３１の片持ち構造の機能を阻害することなく、その自由端である先端部を凹部２８の底部内面に安定して支持して、スペーサ３１の回動のスムーズ化や粘性剤Ｌの漏出防止をより一層確実に行うことができる。
【００５２】
さらに、上記スペーサ３１は先端部を底壁部とする有底中空筒状体で、その凹部２８内に位置する部分の肉厚が略均等であるので、仮に、樹脂製のスペーサ３１を成形したときに変形が生じたとしても、その変形は均一になり、上記スペーサ３１の片持ち支持構造による効果、つまりスペーサ３１の回動のスムーズ化や粘性剤Ｌの漏出防止をさらに確実に行うことができる。
【００５３】
（実施形態２）
図７は本発明の実施形態２を示し（尚、以下の各実施形態では、図１〜図６と同じ部分については同じ符号を付してその詳細な説明は省略する）、スペーサ３１の底壁部に弾性を持たせたものである。
【００５４】
すなわち、この実施形態においては、スペーサ３１は先端部が底壁部とされた有底中空筒状体からなるものであるが、スペーサ３１の内部の底面を平面状とすることで、底壁部においてピボット部３９に対応する中心部よりも周縁部の肉厚が薄く形成されており、この薄肉部３１ａにより、スペーサ３１の底壁部は弾性を有していてピボット部３９がピボット当接部４２との当接状態でスペーサ３１の軸線方向（スペーサ３１の長さ方向）に沿って変形可能となっている。その他の構成は上記実施形態１と同様である。
【００５５】
したがって、この実施形態の場合、スペーサ３１の底壁部が、そのピボット部３９のピボット当接部４２との当接状態で変形可能となるように弾性を有するので、仮に、成形による寸法のばらつきに起因して、スペーサ３１の長さが凹部２８の深さよりも大きく、通常の状態ではピボット部３９がピボット当接部４２と当接してそれ以上嵌入できない状態となっていたとしても、スペーサ３１の底壁部がピボット部３９とピボット当接部４２との当接により開放口側に変位するように弾性変形することで、上記差を吸収することができる。よって、スペーサ３１の基端部をグリップ本体１の第２脚部１ｂにおける収容部２の外側壁２ｂの係止口部４に確実に係止固定することができ、スペーサ３１の凹部２８内への嵌入も容易に行い得る利点がある。
【００５６】
（実施形態３）
図８は実施形態３を示し、上記各実施形態では、スペーサ３１の先端部にピボット部３９を突設し、凹部２８の底部内面にピボット当接部４２を形成しているのに対し、これらをなくし、スペーサ３１の先端部と凹部２８の底部内面とをいずれも円弧面又は平面として、両者間に隙間Ｓ２を形成したものである。また、スペーサ３１の凹部２８内に位置する部分の肉厚は略均等に設けられている。
【００５７】
この実施形態の場合、上記実施形態１のように、ピボット部３９及びピボット当接部４２を設けることによる作用効果は得られないが、その他の効果は実施形態１と同様に奏することができる。
【００５８】
（他の実施形態）
尚、上記実施形態１及び２では、第２取付座１２の支持部１７における凹部２８の底部内面を、スペーサ３１の先端部（底壁部）外面と対応するように中心部で部分的に凹陥した形状にし、この凹陥部分の中心部にピボット当接部４２を形成しているが、この凹部２８の底部内面の全体を、スペーサ３１において係止口部４に係止固定された基端部を略中心とする円弧面からなるピボット当接部４２とすることもできる。
【００５９】
さらに、上記実施形態１及び２では、スペーサ３１の先端部にはピボット部３９を、また凹部２８の底部内面にピボット当接部４２をそれぞれ形成したが、逆に、凹部２８の底部内面には凹部２８と同心状に突出するピボット部を形成する一方、スペーサ３１の先端部外面に、スペーサ３１の先端側が揺動可能となるように上記ピボット部を当接させるピボット当接部を形成してもよく、同様の作用効果が得られる。

BACKGROUND OF THE INVENTION
  The present invention relates to a retractable assist grip that is stored by being rotated from a use position to a storage position when not in use, and particularly relates to a technical field related to measures for stably performing the rotation.
[0002]
[Prior art]
  Conventionally, as a retractable assist grip of this type, a pair of mounting seats fixed to a fixed body such as a vehicle body panel, and a long shape pivotally supported by each of the mounting seats so as to be rotatable by legs. 2. Description of the Related Art A grip body and a biasing means such as a coil spring that biases the grip body from a use position to a storage position are known.
[0003]
  For example, as disclosed in Japanese Patent Application Laid-Open No. 2001-58535, there has been proposed one in which a damper means in which a high-viscosity viscous agent is sealed is integrated between a grip body and a mounting seat.
[0004]
  In this proposal, with respect to the grip body pivotally supported by the mounting seat at the legs at both ends in the longitudinal direction, the mounting seat is mounted on each leg while the grip body is in the retracted position. A recessed portion having a bottomed shape centering on the length direction of the grip body and a fitting projectingly provided on the bottom surface of the recessed portion are formed on the mounting seat on the side on which the damper means is provided to form a housing portion for accommodating a part. A spacer having a fitting portion which is formed in a cylindrical portion having a shaft and is rotatably fitted in the recess and into which the fitting shaft is fitted. The other side wall of the accommodating portion is supported on the cylindrical portion on the bottom side of the concave portion so as to be relatively rotated, and is engaged between the outer peripheral surface of the spacer and the inner peripheral surface of the concave portion. In addition, a viscosity agent is interposed between the outer peripheral surface of the insertion shaft and the inner peripheral surface of the insertion portion. So that cause resistance to the rotation of the spacer, that the grip body by the viscosity.
[0005]
  On the other hand, in EP Patent Publication 0875420A2, a tapered recess having a small diameter toward the bottom side is formed in one mounting seat, and a tapered taper spacer is inserted into the recess from the front end side. The support shaft is inserted into the center hole of the spacer and engaged with the rotation integrally with the key, and both ends of the support shaft are rotatably fixed to the leg portion of the grip body, and the tapered inner peripheral surface of the recess and the spacer Viscous agent is filled in and sealed in the gap between the tapered outer peripheral surface of the spacer and when the grip body rotates around the support shaft, the viscosity of the spacer, that is, the grip body, depends on the viscosity of the adhesive between the spacer and the recess. There has been proposed one provided with a damper means for causing resistance to rotation.
[0006]
[Problems to be solved by the invention]
  By the way, the grip body is generally made of resin, and the resin grip body is generally manufactured by molding. However, in that case, it is inevitable that the grip body is deformed to some extent due to shrinkage at the time of molding the resin, and since the grip body is long, the axes of both legs of the grip body are centered. In either case, it is difficult to accurately coincide with the axis of the support portion of the corresponding mounting seat at the same time, and there is a possibility that they are displaced on either side. When this deviation occurs, the grip body does not rotate smoothly, and even if there is a rotational biasing force of the biasing means, it does not return from the use position to the retracted position, or the sealing of the viscous agent becomes insufficient. Will cause problems such as leakage.
[0007]
  The present invention has been made in view of such points, and its object is to improve the structure of the damper means provided between the leg portion of the grip body and the mounting seat in the retractable assist grip as described above. Even if the resin grip body is slightly deformed by molding, the grip body can be smoothly rotated without being affected by this, preventing leakage of the viscous agent, The purpose is to improve the operational stability.
[0008]
[Means for Solving the Problems]
  In order to achieve the above object, according to the present invention, the spacer is fixed at the base end to the leg portion of the grip body and is rotatably fitted so as to define a gap for filling the viscous agent in the concave portion of the mounting seat. TheIt should have a hollow shape with a bottomThe spacer support structure is a cantilever structure so that only the base end portion is fixed to the leg portion of the grip body.
[0009]
  Specifically, according to the first aspect of the present invention, a pair of mounting seats fixed to the fixed body, and a long resin grip that is pivotally supported by these mounting seats so as to be rotatable at the leg portions, respectively. A retractable assist grip provided with a main body and a biasing means for biasing the grip main body from a use position to a retracted position is a premise.
[0010]
  And the specific matters as the features are as follows. That is, of the legs, the surface facing the fixed body when the grip body is in the retracted position has two side walls facing the length direction of the grip body, and the grip body is in the retracted position. A housing portion for housing a part of the mounting seat is cut out.
[0011]
  Further, at least one of the pair of mounting seats is formed with a support portion having a bottomed cylindrical recess extending in the length direction of the grip body, and the opening of the recess is formed in the housing portion. One of the two side walls is located on the side wall, and the bottom is located on the other side wall.
[0012]
  Furthermore, a locking port portion is formed concentrically with the recess in one of the two side walls of the housing portion facing the opening of the recess.
[0013]
  In the recess of the support portion, the front end portion is positioned on the bottom side of the recess, and the base end portion is inserted through the locking port portion of the side wall of the housing portion and locked in a non-rotatable manner. A spacer is rotatably fitted with the tip end as a free end.
[0014]
  The spacer is formed of a hollow cylindrical body having a bottom portion with a bottom wall portion and an opening at the base end portion, and at least a portion of the spacer located in the concave portion has a substantially uniform thickness. It has been.
[0015]
  In addition, the gap between the inner peripheral surface of the recess and the outer peripheral surface of the spacer and the gap between the tip of the spacer and the bottom of the recess are filled with a viscous agent.
[0016]
  Further, a sealing material is interposed between the opening of the recess and the spacer to prevent the viscous agent from flowing out of the gap.
[0017]
  According to the above configuration, the grip body is pivotally supported by the leg portions on the pair of mounting seats fixed to the fixed body, and the grip body is rotated from the use position to the storage position by the urging means. Be energized. Further, at least one of the pair of mounting seats is provided with a support portion having a recess, and the leg portion of the grip body corresponding to the mounting seat is rotatably fitted in the recess. A resin-made spacer is inserted through the locking port portion of the side wall of the housing portion in the leg portion at the base end portion thereof, and is locked so as not to rotate, and a gap between the inner peripheral surface of the recess and the outer peripheral surface of the spacer And a viscous agent is interposed in a gap between the tip of the spacer and the bottom of the concave portion in a state of being sealed with a sealing material, so that a damper action is obtained by the viscosity of the viscous agent, and the urging means As a result, when the grip body is rotated from the use position to the storage position, resistance is generated in the rotation of the grip body, and the grip body is slowly rotated, so that a high-quality feeling can be obtained. Further, in the retracted position of the grip body, a part of the mounting seat is accommodated in the accommodating portion of the leg portion.
[0018]
  At that time, the resin spacer that is non-rotatably locked to the locking opening on the side wall of the housing portion in the leg portion of the grip body rotates around the spacer tip in the recess of the support portion of the mounting seat. Since it is movably inserted and only its base end is locked and fixed to the leg of the grip body, the support structure of this spacer is cantilevered, and the resin grip body is contracted during molding, etc. Even if the shaft centers of both legs are displaced with respect to the shaft center of the corresponding mounting seat support, the displacement is absorbed by the relative displacement of the free end of the cantilevered spacer. Can do. As a result, the grip body can be rotated smoothly and the grip body can be reliably returned from the use position to the retracted position, and the spacer is placed in the recess of the mounting seat with good sealing performance of the viscous agent between the two. It can be sealed to prevent the viscous agent from leaking out.
[0019]
  Moreover, since the said spacer consists of a hollow cylindrical body by which the front-end | tip part located in the bottom part side of a recessed part was made into the bottom wall part, the resin usage-amount of a spacer can be reduced and cost can be reduced. Moreover, since the thickness of at least the portion of the spacer located in the recess is substantially uniform, even if deformation occurs when the resin spacer is molded, the deformation can be made uniform. The effect of the spacer cantilever support structure, that is, the smooth rotation of the spacer It is possible to more reliably prevent the viscous agent from leaking out.
[0020]
  According to the invention of claim 2, a pivot portion that protrudes concentrically with the spacer or the recess is formed on one of the outer surface of the tip of the spacer or the inner surface of the bottom of the recess, while the outer surface of the tip of the spacer or the bottom of the recess The other inner surface is formed with a pivot abutting portion for abutting the pivot portion so that the front end side of the spacer can swing.
[0021]
  According to this configuration, the free end of the spacer tip is supported so as to be swingable by the contact between the pivot portion and the pivot contact portion with respect to the inner surface of the bottom of the recess. Can be stably supported on the inner surface of the bottom of the recess without hindering the function of the cantilever structure of the spacer, and the smooth rotation of the spacer and the prevention of the leakage of the viscous agent can be more reliably performed..
[0022]
  Claim3In the invention of the above,2In the retractable assist gripSaThe bottom wall portion is characterized by having elasticity so that the pivot portion can be deformed along the spacer center line direction in a contact state with the pivot contact portion.
[0023]
  As a result, even if the length of the spacer is larger than the depth of the recess due to a manufacturing error, the difference between the spacer and the bottom wall of the spacer is elastic in the contact state between the pivot portion and the pivot contact portion. It can be absorbed by being deformed, and the base end portion of the spacer can be reliably locked to the locking port portion of the side wall of the accommodating portion in the leg portion of the grip body, and the spacer can be easily fitted into the recess.
[0024]

In addition, 27a is a sinking prevention hole provided in the front end surface of the shaft part 27, and is for preventing the sink of the shaft part 27 during molding.
[0035]
  The second leg portion 1b of the grip body 1 has an outer wall facing the opening of the recess 28 of the support portion 26 in the second mounting seat 12 among the inner and outer side walls 2a and 2b of the housing portion 2. A locking port 4 having a substantially semi-elliptical shape (or other shape) may be formed through 2b so as to be concentric with the recess 28. On the other hand, a shaft support hole 5 is formed in the inner wall 2a concentrically with the locking port portion 4 (recess 28), and the shaft portion 27 of the support portion 26 is rotatably fitted in the shaft support hole 5. Has been. In contrast to the above, a locking port may be provided in the inner wall 2a and a shaft support hole may be provided in the outer wall 2b.
[0036]
  Further, a resin spacer 31 made of, for example, POM or the like is provided in the concave portion 28 of the support portion 26 from the front end side between the outer peripheral surface and the inner peripheral surface of the concave portion 28, and the front end portion of the spacer 31 and the bottom portion of the concave portion 28. Are inserted so as to be rotatable with substantially constant gaps S1 and S2 between them. The spacer 31 is inserted into the recess 28 from the outside of the outer wall 2b of the housing portion 2 of the second leg 1b through the engaging port 4 of the outer wall 2b. The cross-sectional shape of the outer peripheral surface is formed in the same shape as the above-described locking port portion 4, and the base end portion of the spacer 31 is locked to the locking port portion 4 so as not to rotate (integrated with rotation). Thus, the spacer 31 is fitted into the recess 28 so as to be rotatable with the tip end located on the bottom side of the recess 28 as a free end.
[0037]
  The spacer 31 is a bottomed hollow cylindrical body having a bottom wall portion at the bottom side of the concave portion 28 and an opening at the base end portion, and a portion located in the concave portion 28 of the spacer 31. The wall thickness is substantially even. Further, a lid 32 that opens and closes the opening is integrally formed on the peripheral edge portion of the opening at the base end portion of the spacer 31 through a thin hinge 33, and an engagement protrusion 32a is formed at the distal end portion of the lid 32. Is formed in part of the base end portion of the spacer 31, and an engagement hole 37 that can be engaged with the engagement protrusion 32a at the distal end portion of the lid 32 is provided. Is engaged with the engagement hole 37 at the base end portion of the spacer 31 to hold the lid 32 in a closed state.
[0038]
  For example, four rectangular openings 34, 34,... Are formed at intervals in the circumferential direction at the base end portion of the spacer 31, and the portion excluding the opening 34 is more than the portion fitted in the recess 28. The outer peripheral surface is provided with a locking projection 36, and the spacer 31 is fitted into the recess 28 of the second mounting seat 12 from the distal end side. By positioning the locking projection 36 on the inner side of the outer wall 2b while allowing the locking port portion 4 of the outer wall 2b to be bent and deformed together with the locking projection 36, the thin-walled portion 35 of the outer wall 2b is positioned. The portion is locked to the locking port 4 so as not to rotate (integrated with rotation). In the state where the base end portion of the spacer 31 is locked to the locking port 4, the lid 32 is rotated around the thin hinge 33 and opened and closed.
[0039]
  The outer surface of the tip (bottom wall) of the spacer 31 is concentric with the spacer 31 by projecting the outer surface of the bottom wall into a tapered shape so that the cross section of the tapered surface is a concave arc surface. A protruding pivot portion 39 is formed. Further, the bottom surface of the spacer 31 is formed in a tapered shape corresponding to the pivot portion 39 on the outer surface of the bottom wall so that the thickness of the spacer 31 is substantially uniform.
[0040]
  On the other hand, the inner surface of the bottom of the recess 28 is partially recessed so as to correspond to the outer surface of the tip (bottom wall) of the spacer 31, and the tip of the spacer 31 swings at the center of the recess. A pivot abutting portion 42 for abutting the pivot portion 39 is formed so as to be possible. The pivot abutting portion 42 has an arcuate surface whose center is the base end portion that is locked and fixed to the locking port 4 in the spacer 31. The pivot abutting portion 42 causes the pivot portion 39 to slidably contact. Thus, the front end side of the spacer 31 can be swung in the recess 28.
[0041]
  Further, a tapered gap S1 between the inner peripheral surface of the recess 28 in the support portion 26 of the second mounting seat 12 and the outer peripheral surface of the spacer 31 fitted in the recess 28, and communication with the gap S1. Each of the gaps S2 between the tip of the spacer 31 and the bottom of the recess 28 is filled with a viscous agent L made of a liquid having a high viscosity (preferably 100000 cps or more) such as silicon.
[0042]
  Further, a sealing material 45 made of an O-ring or the like for preventing the viscous agent L from flowing out of the gaps S1 and S2 is interposed between the opening of the recess 28 and the spacer 31. Specifically, a seal groove 46 is formed over the entire circumference of the spacer 31 in a portion corresponding to the inner peripheral surface near the opening of the recess 28 on the outer peripheral surface of the spacer 31. A sealing material 45 is fitted. The outer peripheral surface of the sealing material 45 is in pressure contact with the sealing surface 47 on the inner peripheral surface near the opening of the recess 28, and the second mounting seat 12 is supported by pressure contact with the sealing surface 47 of the sealing material 45. The gap S1 between the inner peripheral surface of the concave portion 28 and the outer peripheral surface of the spacer 31 in the portion 26 and the gap S2 between the tip portion of the spacer 31 and the bottom portion of the concave portion 28 are sealed, and the gaps S1, S2 are sealed. The outflow of the viscous agent L from is prevented.
[0043]
  And the clearance gap S2 between the inner peripheral surface of the recessed part 28 in the support part 26 of the above 2nd attachment seat 12 and the outer peripheral surface of the spacer 31, and the clearance gap S2 between the front-end | tip part of the spacer 31 and the bottom part of the recessed part 28 are shown. Damper means 24 for generating torque that serves as a rotational resistance when the grip body 1 rotates is formed by the viscous agent L filled in each.
[0044]
  The operation of assembling the assist grip G of the above embodiment to the vehicle body panel P in the second leg portion 1b of the grip body 1 will be described. As shown in FIG. 6, the seal material 45 is fitted in the seal groove 46 on the outer periphery of the spacer 31 in advance. At the same time, the required amount of the viscous agent L is filled into the recess 28 of the second mounting seat 12 from the opening. The filling amount (necessary amount) of the viscous agent L at this time is the volume of the gap S1 between the outer peripheral surface of the spacer 31 and the inner peripheral surface of the recess 28, and between the tip of the spacer 31 and the bottom of the recess 28. Is set slightly larger than the total sum of the volumes of the gaps S2. In this way, when the spacer 31 is fitted into the recess 28 and assembled to the second mounting seat 12, the viscosity agent L slightly leaks from both the gaps S1 and S2, and the respective gaps S1, The viscous agent L is filled in S2.
[0045]
  First, the distal end portion of the shaft portion 27 of the second mounting seat 12 is inserted into the shaft support hole 5 of the inner wall 2a of the housing portion 2 in the second leg portion 1b of the grip body 1, and then the housing portion 2 The spacer 31 is inserted into the locking opening 4 in the outer side wall 2b from the front end side, and is inserted into the recess 28 of the second mounting seat 12 from the opening, and the base end of the spacer 31 is connected to the locking opening. Locked to the part 4. When the spacer 31 is completely inserted into the concave portion 28 of the second mounting seat 12 to an appropriate position, the outer peripheral portion of the sealing material 45 is pressed against the seal surface 47 on the inner peripheral surface near the opening of the concave portion 28. Thus, the gap between the seal surface 47 and the outer peripheral surface of the spacer 31 is closed in an airtight manner so as to be relatively rotatable, and the gap S1 between the outer peripheral surface of the spacer 31 and the inner peripheral surface of the recess 28, and the spacer The viscous agent L is sealed in the gaps S <b> 2 between the tip of 31 and the bottom of the recess 28.
[0046]
  The assist grip G to which the second mounting seat 12 is assembled in this manner is inserted into the bolt insertion hole 15 of the mounting seat body 13 in the second mounting seat 12 so that the second mounting seat 12 is attached to the vehicle body panel P. By being fastened to the nut N on the back surface, it is assembled to the vehicle body panel P via the second mounting seat 12. Thereafter, the hinged lid 14 of the second mounting seat 12 is closed to cover and hide the mounting bolt B.
[0047]
  On the other hand, in the first mounting seat 11, the first leg 1 a of the grip body 1 is rotatably supported by the support shaft 8 and the torsion coil spring 7 is attached. Thereafter, the first mounting seat 11 is assembled to the vehicle body panel P substantially together with and in the same manner as the second mounting seat 12.
[0048]
  Therefore, in the assist grip G of this embodiment, the grip body 1 is normally rotated and urged by the urging force of the torsion coil spring 7 and is positioned at the storage position. Part of the mounting seats 11 and 12 are accommodated in the accommodating portions 2 of the leg portions 1a and 1b, respectively. When the vehicle occupant uses the assist grip G, the grip body 1 may be grasped by hand and rotated to the use position against the urging force of the torsion coil spring 7. Further, when the use of the assist grip G is stopped, when the passenger releases his / her hand from the grip body 1, the grip body 1 is rotated from the use position to the retracted position with respect to the mounting seats 11 and 12 by the biasing force of the torsion coil spring 7. Return while.
[0049]
  When the grip body 1 is rotated from the use position to the storage position (the same thing occurs when the grip body 1 is rotated from the storage position to the use position), the housing portion 2 in the second leg 1b of the grip body 1 is used. The spacer 31 is fixed to the outer wall 2b of the housing portion 2 so that the inner wall 2a of the second mounting seat 12 is not rotatable. 28, respectively, but in the gap S1 between the outer peripheral surface of the spacer 31 and the inner peripheral surface of the recess 28 and the gap S2 between the tip of the spacer 31 and the bottom of the recess 28, respectively. Since L is filled, resistance (torque) is generated in the rotation of the spacer 31 and the grip body 1 integrated therewith due to the viscosity of the viscosity agent L. As a result, the grip body 1 slowly rotates from the use position to the retracted position, so that no tapping sound is generated by the grip body 1 being strongly hit against the vehicle body panel P, and a high-quality feeling can be obtained. It is done.
[0050]
  At that time, the resin spacer 31 that is locked at the base end portion so as not to rotate at the locking port portion 4 of the outer wall 2b of the housing portion 2 in the second leg portion 1b of the grip body 1 is the second The spacer 31 is rotatably fitted in the recess 28 of the support portion 26 with the distal end portion of the spacer 31 as a free end, and only the base end portion is fixed to the outer wall 2b of the accommodating portion 2 of the second leg portion 1b. The support structure of the spacer 31 is a cantilever structure. For this reason, the resin-made grip body 1 is deformed due to shrinkage or the like at the time of molding, and the shaft centers of both leg portions 1a and 1b are respectively corresponding to the shaft centers of the support portions 17 and 26 of the mounting seats 11 and 12, respectively. Even if there is a deviation, the deviation can be absorbed by the relative displacement of the free end on the front end side of the spacer 31 in the cantilever state. As a result, the grip body 1 can be smoothly rotated, and the grip body 1 can be reliably returned from the use position to the retracted position by the urging force of the torsion coil spring 7. Moreover, by absorbing the displacement of the axial center, the seal material 45 on the spacer 31 side is effectively pressed against the seal surface 47 on the inner peripheral surface of the recess 28, so that the gap between the recess 28 of the second mounting seat 12 and the spacer 31 is reached. The viscous agent L can be reliably enclosed in the gaps S1 and S2, and leakage of the viscous agent L can be prevented. As a result, the reliability and operation stability of the retractable assist grip G can be improved.
[0051]
  Further, a pivot portion 39 protrudes from the outer surface of the distal end portion of the spacer 31, and a pivot abutting portion 42 that abuts the pivot portion 39 is formed at the center of the inner surface of the bottom of the concave portion 28 facing the outer surface of the distal end portion of the spacer 31. Since the leading end side of the spacer 31 can be swung by the abutment between the pivot portion 39 and the pivot abutting portion 42, the free end of the leading end portion of the spacer 31 is placed on the bottom inner surface of the recess 28 and the pivot portion 39. It can be pivotably supported by abutting with the pivot abutting portion 42, and the free end of the tip can be stabilized on the inner surface of the bottom of the recess 28 without impeding the function of the cantilever structure of the spacer 31. Thus, smooth rotation of the spacer 31 and prevention of the leakage of the viscous agent L can be more reliably performed.
[0052]
  Further, the spacer 31 is a hollow cylindrical body having a bottom wall portion at the tip, and the thickness of the portion located in the concave portion 28 is substantially uniform. Therefore, the resin spacer 31 is temporarily formed. Even if deformation occurs, the deformation becomes uniform, and the effect of the cantilevered support structure of the spacer 31, that is, smooth rotation of the spacer 31 and prevention of leakage of the viscous agent L can be more reliably performed. it can.

The wall portion is elastic and can be deformed along the axial direction of the spacer 31 (the length direction of the spacer 31) while the pivot portion 39 is in contact with the pivot contact portion. Other configurations are the same as those of the first embodiment.
[0055]
  Therefore, in the case of this embodiment, since the bottom wall portion of the spacer 31 has elasticity so that it can be deformed in a contact state with the pivot contact portion 42 of the pivot portion 39, the dimensional variation due to molding is assumed. Therefore, even if the length of the spacer 31 is larger than the depth of the recess 28 and the pivot portion 39 is in contact with the pivot contact portion 42 and cannot be fitted any more in a normal state, the spacer 31 The above-mentioned difference can be absorbed by elastically deforming the bottom wall portion of the base plate so that the bottom wall portion is displaced toward the opening by the contact of the pivot portion 39 and the pivot contact portion 42. Therefore, the base end portion of the spacer 31 can be reliably locked and fixed to the locking port portion 4 of the outer wall 2b of the housing portion 2 in the second leg portion 1b of the grip body 1 and into the concave portion 28 of the spacer 31. There is an advantage that can be easily inserted.
[0056]
  (Embodiment 3)
  FIG. 8 shows a third embodiment. In each of the above-described embodiments, the pivot portion 39 projects from the tip of the spacer 31 and the pivot abutting portion 42 is formed on the inner surface of the bottom of the recess 28. In other words, the tip of the spacer 31 and the bottom inner surface of the recess 28 are both arcuate or flat, and a gap S2 is formed between them. Moreover, the thickness of the part located in the recessed part 28 of the spacer 31 is provided substantially equally.
[0057]
  In the case of this embodiment, the effect by providing the pivot part 39 and the pivot contact part 42 cannot be obtained as in the first embodiment, but the other effects can be obtained as in the first embodiment.
[0058]

The pivot abutting portion 42 is formed at the center of the recessed portion, and the entire bottom inner surface of the recessed portion 28 is substantially the base end portion that is locked and fixed to the locking port 4 in the spacer 31. It can also be set as the pivot contact part 42 which consists of a circular arc surface as a center.
[0059]
  Furthermore, in the first and second embodiments, the pivot portion 39 is formed at the tip of the spacer 31 and the pivot abutting portion 42 is formed at the bottom inner surface of the recess 28. While forming a pivot portion concentrically protruding with the recess 28, a pivot abutting portion is formed on the outer surface of the distal end portion of the spacer 31 so as to abut the pivot portion so that the distal end side of the spacer 31 can swing. The same effects can be obtained.
