Abstract
ウォーム歯6aとウォームホイール4との噛合状態を、動力の伝達方向に拘らずほぼ一定にする。そして、操舵力がステアリングホイールの回転方向により変化しにくく、しかも、不快な異音や振動が発生することがない構造を実現する。
ウォーム軸7aの先端部を支持するための転がり軸受8aを構成する外輪20の外周面と保持円筒部24の内周面との間に、弾性保持部材21を設ける。弾性保持部材21は、半円筒部22及びこの半円筒部22の円周方向両端部からウォームホイール4の側に延出する1対の弾性腕部を備える。そして、半円筒部22により外輪20のウォームホイール4と反対側半部を抱持すると共に、1対の弾性腕部の先端部を保持円筒部24の内周面に弾性的に当接させる。この構成により、ウォーム軸7aの先端部がウォーム軸4の軸方向に変位しにくくして、上記課題を解決する。
