Abstract

操舵補助力を発生するための電動モータ(16)の出力回転を駆動ギヤ(22)および従動ギヤ(21)を介して操舵機構(64)に伝達する電動パワーステアリング装置(1)が提供される。ハウジング(8)は、駆動ギヤ(22)と一体回転する軸(20)の一方の端部(23)を軸受(26)を介して駆動ギヤ(22)の径方向従動ギヤ(21)側に偏倚可能に支持するための支持孔(28)を含む。駆動ギヤ(22)を従動ギヤ(21)側に付勢する付勢部材(33)は、軸受(26)の外輪(36)の外周面(58)に嵌め合わされ且つ支持孔(28)の内周面(42)に対向する円弧状の主体部(47)を含む。主体部(47)の一対の円弧端(48,49)に、主体部(47)の周方向移動を規制する一対の移動規制部(50,51)がそれぞれ設けられる。軸受(26)を介して駆動ギヤ(22)を従動ギヤ(21)側へ付勢する弾性舌片(52)が、一方の移動規制部(50)のみに設けられる。
