Abstract

電動モータ（７）を有する駆動部（２）と、駆動部（２）の回転運動を直線運動に変換する運動変換機構部（３）とが直列に配置され、運動変換機構部（３）が、駆動部（２）の回転運動を受けて回転するナット（３０）と、ナット（３０）の回転に伴って直線運動するねじ軸（３１）とを有する電動アクチュエータ（１）において、駆動部（２）と運動変換機構部（３）の間のトルク伝達経路中に、駆動部（２）の回転トルクを伝達可能に連結された内方部材（Ｎ）と外方部材（Ｍ）が設けられ、内方部材（Ｎ）が、外方部材（Ｍ）の内周にすきまばめされている。外方部材（Ｍ）は、減速機（８）を構成する遊星ギヤキャリア（５１）で、また、内方部材（Ｎ）は、ナット（３０）で構成することができる。
