Description
しかも、前記緩衝部材は、前記緩衝作用時において、前記軸継手の内側面と前記ハウジングの軸方向他端面ないしエンド部材の外端面に挟まれて圧縮変形するため、前記係合突部が前記係止溝内に入り込む方向へと弾性変形することとなり、これによって、前記緩衝部材と前記ラック軸の結合力が高められ、前記緩衝部材の軸方向の位置ずれを防止することにも供される。
前記軸継手における前記ラック軸との結合部外周に、前記雌ねじ部に螺合する雄ねじ部を形成し、
前記係止溝を、前記軸継手の雄ねじ部がねじ込まれる前記ラック軸の軸方向領域の範囲内に形成したことを特徴とする請求項1又は2に記載のステアリング装置。
3a…ラックハウジングの端面(ハウジングの軸方向他端面)
8…シリンダチューブ(ハウジング)
11…ラック軸
11a…ラック軸の端面
12…エンドキャップ(エンド部材)
12a…エンドキャップの外端面(エンド部材の外端面)
13…ボールジョイント(軸継手)
13b…保持部の外底面(軸継手の対向端面)
14…タイロッド
15…緩衝部材
16…係止溝
17…係合突部
Claims (2)
- ハウジング内に軸方向へ移動可能に配設されたラック軸と、
該ラック軸の両端部に結合された軸継手と、
該軸継手に回動自在に支持されて車輪と連係するタイロッドと、
前記ハウジングの軸方向一端部に設けられて前記ラック軸を摺動自在に支持するエンド部材と、
前記ラック軸の両端部に配設され、該ラック軸の最大摺動時において前記ハウジングの軸方向他端面又は前記エンド部材の外端面に当接することにより、前記軸継手の衝突を緩衝するほぼ円環状の緩衝部材と、を備え、
前記緩衝部材は、その内周面に突設された係合突部が前記ラック軸の両端部外周面に設けられた円環状の係止溝に嵌合するかたちで前記ラック軸の両端部外周に配設されることにより、前記ラック軸の軸方向両端面を平坦な円環状に連続して形成すると共に、その外径が前記ハウジングの軸方向他端面又は前記エンド部材の外端面に対向する前記軸継手の内側面の外径よりも小径に設定されることにより、前記ラック軸の最大摺動時において、その外端面全体が前記軸継手の内側面によって支持された状態で前記ハウジングの軸方向他端面又は前記エンド部材の外端面と当接することを特徴とするステアリング装置。 - ハウジング内に軸方向へ移動可能に配設されたラック軸と、
