Abstract
Description
車体又はスライドドアに固定されるブラケットと、
前記ブラケットの外面に形成された板状取付部と、
前記板状取付部に形成され、前記板状取付部の板厚方向に形成されたロック孔と、
前記ロック孔の開口縁に沿って形成された撓みロック片と、
前記板状取付部に形成され、前記ロック孔との間で前記撓みロック片を挟むように配され、前記撓みロック片が前記ロック孔の開口面積を拡げるように弾性撓みすることを許容する撓み許容孔と、
前記ブラケットに対し前記板状取付部の外面を覆うように組み付けられる組付け部材と、
前記組付け部材に形成され、前記ロック孔に嵌入されるロック用嵌入部と、
前記ロック用嵌入部に形成され、前記ロック用嵌入部が前記ロック孔に嵌入した状態で前記撓みロック片と係止可能なロック突起とを備えているところに特徴を有する。
この構成の技術的意義は、次の通りである。撓みロック片は弾性撓みするときに湾曲変形し、撓みロック片の長さ方向に沿った両側縁部のうち湾曲の内周側がロック孔に臨み、湾曲の外周側が撓み許容孔に臨む。この点に着目し、撓み許容孔の形成領域をロック孔の形成領域よりも広い範囲とした。これにより、撓みロック片は撓み許容孔側へ変形し易くなるので、ロック突起が撓みロック片を弾性撓みさせるときの抵抗が小さくて済む。
この構成によれば、ロック突起が撓みロック片に当接する位置は、撓みロック片の弾性変位量が最大となる長さ方向略中央部のみである。したがって、撓みロック片が弾性撓みしたときにロック突起が受ける抵抗が小さくて済む。
この構成によれば、組付け部材をブラケットに組み付ける際には、ロック孔が組付け部材で隠れるため、ロック用嵌入部とロック孔の位置合わせを目視で行うことが難しい。しかし、上記構成によれば、ブラケットの外面に形成されている摺接面とガイド部に、組付け部材の摺接部を目視しながら位置合わせすることができるので、ロック用嵌入部を確実にロック孔に嵌入させることができる。
この構成によれば、組付け部材をブラケットに組み付ける際に、ブラケットに対して組付け部材を位置決めすることができる。
この構成によれば、収容空間の開口部を覆うことにより、走行時の風切り音を低減することができる。
以下、本発明を具体化した実施例1を図1~図22を参照して説明する。図21に示すのは、本実施例1の取付け部材Aが取り付けられる自動車Vである。自動車Vの車体Bの側面の乗降口Eは、スライドドアDによって開閉されるようになっている。車体BとスライドドアDとの間には、スライドドアDに設けた電装品への給電等を行うための可撓性を有する細長い電線ガイド装置Gが架け渡されている。電線ガイド装置Gは、ワイヤーハーネス(図示省略)を筒状の外装体で包囲した周知の形態のものである。本実施例1の取付け部材Aは、電線ガイド装置Gの一方の端部を、車体Bに固定するための手段として機能する。
取付け部材Aは、合成樹脂製のブラケット10と、合成樹脂製のアッパ部材30(請求項に記載の組付け部材)と、合成樹脂製のロア部材40(請求項に記載の組付け部材)とを備えて構成されている。尚、以下の取付け部材Aに関する説明において、前後の方向については、図1~3,5,8における左方を、前方と定義する。また、上下方向については、図1,4~7,9~11,15にあらわれる向きを、そのまま上方、下方と定義する。左右の方向については、図2における下方及び図3,8における上方を、右方と定義する。
図10に示すように、ブラケット10は、前後方向に貫通した角筒部11と、角筒部11の左側面下端部から水平左方へ張り出した張出部12とを備えている。張出部12には、上下方向に貫通するボルト孔13が形成されている。角筒部11は、左右両側壁部14と、両側壁部14の上端同士を連結する水平な第1板状取付部15と、両側壁部14の下端同士を連結する第2板状取付部16とを備えている。
図11に示すように、アッパ部材30は、水平な板状本体部31を有する単一部品である。板状本体部31の平面視形状は、前端側領域の幅寸法が後端側領域の幅寸法よりも大きくて、略T字形をなしている。図7に示すように、板状本体部31の後端部下面には、左右対称な板状をなす一対の第1ロック用嵌入部32が下向きに突出している。第1ロック用嵌入部32は、その板厚方向が左右方向を向くように配されている。
図15に示すように、ロア部材40は、平面視が方形をなす水平な基板部41と、基板部41の前端縁に連なる段差部42と、段差部42の前端縁に連なる覆い部43とを備えている。基板部41の上面後端部には、左右対称な一対の第2ロック用嵌入部44と、第2ロック用嵌入部44の内側面から突出する左右対称な一対の第2ロック突起45とが形成されている。第2ロック用嵌入部44と第2ロック突起45は、上記第1ロック用嵌入部32と第1ロック突起33を上下反転させた形態であるから、詳しい説明は省略する。
ブラケット10に対するアッパ部材30の組付けと、ブラケット10に対するロア部材40の組付けは、どちらを先に行ってもよい。まず、ブラケット10とアッパ部材30の組付け手順を説明する。アッパ部材30は、板状本体部31をブラケット10の上方から第1板状取付部15の上面に被せるように接近させる。このとき、左右両摺接部34でブラケット10を挟み、両摺接部34の内面をブラケット10の摺接面25に摺接させるとともに、両摺接面25の前後両側縁を前後一対のガイド部24に摺接させる。この摺接作用により、アッパ部材30がブラケット10に対し前後方向及び左右方向に位置決めされる。
