To prevent an excessive load from acting on a structure member, when a direct-acting member is strongly pushed in an axial direction of a structure member of an electric direct-acting actuator.SOLUTION: An electric direct-acting actuator 14 is equipped with a direct-action converting mechanism 24 which converts rotary motion of a rotating member 25 rotatable around an axis and immovable in an axial direction by electric motor 15, into linear motion of a direct-acting member 26 not rotatable around the axis and movable in the axial direction. The rotating member 25 and the direct-acting member 26 are respectively provided with regulating means 42 and 43, and both regulating means 42 and 43 abut on each other in a circumferential direction of the rotations, thereby regulating the linear motion of the direct-acting member 26.SELECTED DRAWING: Figure 1

    【課題】直動部材が電動式直動アクチュエータの構成部材の軸方向に強く押し込まれて、この構成部材に過大な負荷が作用するのを防止すること。【解決手段】電動モータ15によって軸周りに回転可能かつ軸方向に移動不能とした回転部材25の回転運動を、前記軸周りに回転不能かつ軸方向に移動可能とした直動部材26の直線運動に変換する直動変換機構24を備えた電動式直動アクチュエータ14において、回転部材25及び直動部材26のそれぞれに規制手段42、43が設けられており、両規制手段42、43が前記回転の周方向に互いに当接することによって、直動部材26の直線運動を規制することを特徴とする電動式直動アクチュエータを構成する。【選択図】図1
