Abstract

　軸方向長さが短い電動式直動アクチュエータを提供する。 　電動モータ１９で駆動する回転軸１４の外径面と、その回転軸１４の外径側に固定された外輪部材１５の内径面との間に、回転軸１４の回転に伴って自転しながら公転する複数の遊星ローラ１６を介在させ、外輪部材１５の内径面に螺旋凸条２５を設け、その螺旋凸条２５と係合する螺旋溝２６を遊星ローラ１６の外径面に設け、遊星ローラ１６と軸方向に対向する遊星キャリア１７を設け、その遊星キャリア１７と遊星ローラ１６の間に、遊星ローラ１６の自転運動が遊星キャリア１７に伝達するのを遮断するスラスト玉軸受２７を設けた電動式直動アクチュエータにおいて、遊星ローラ１６の軸方向端面に、スラスト玉軸受２７の軌道面２８を形成する。
