Abstract
Description
また、本発明の別の態様として、ステアリングホイールのシャフトを保持するコラムを車両本体に対し動かして、ステアリングホイールの位置を調整可能なステアリング装置であって、前記コラムを車両本体に対し固定及び固定解除するための回動レバーと、前記回動レバーの回動をその回動の軸方向の運動に変えて前記コラムを固定及び固定解除するカムと、前記カムを保持し、前記回動レバーの回動時に前記カムとの間で摺動するスリーブと、前記スリーブを前記カムの摺動面に押し付ける押付け部材と、を有する、ステアリング装置を含む。
前記スリーブには、前記回動レバー、或いは前記回動レバーと前記スリーブとの間に介在される介在部材と摺動する摺動部が設けられていてもよい。
前記回動レバー或いは前記介在部材が円板状部を有し、前記摺動部は、前記円板状部が嵌め込まれる円弧状の溝を有するものであってもよい。
前記摺動部にグリースが塗布されていてもよい。
前記押付け部材は、弾性部材であってもよい。
前記摺動部内にグリースが塗布されていてもよい。
図1は、第1実施形態に係るステアリング装置1の全体構成の一例を示す。
第2実施形態に係るステアリング装置1は、第1実施形態に係るリングバネ125の代わりに、バネクリップ125’が設けられている点に特徴がある。従って、第1実施形態に係るステアリング装置1と共通する図面(図1~図5)については図示を省略するとともに、対応する部分については同一符号を付し、詳細な説明を割愛する。
