To provide an actuator and a vehicle door opening/closing actuator that can reduce noises when driven.SOLUTION: An actuator of the present invention includes: a screw shaft 38 that is driven rotationally by receiving rotational forces from a shaft 14 of a motor 11; a nut member 58 that is secured in an inner tube 56 and linked to the screw shaft 38, and that moves along the axial direction of the screw shaft 38 together with the rotation of the screw shaft 38; and a stopper 60 that is provided on one end 38b opposite the motor 11 of the screw shaft 38 and that prevents the nut member 58 from coming out of the screw shaft 38. The stopper 60 includes a restriction member 61 that elastically restricts an axial tilt of the screw shaft 38. The restriction member 61 always contacts the inner peripheral surface of the inner tube 56 slidably.SELECTED DRAWING: Figure 3

    【課題】駆動時の騒音を低減できるアクチュエータ及び車両ドア開閉用アクチュエータを提供する。【解決手段】モータ部11のシャフト14の回転力を受けて回転駆動するスクリュー軸38と、インナーチューブ56に固定されるとともにスクリュー軸38に連係され、このスクリュー軸38の回転にともなってスクリュー軸38の軸方向に沿って移動するナット部材58と、スクリュー軸38のモータ部11とは反対側の他端38bに設けられ、ナット部材58のスクリュー軸38からの抜けを防止するストッパ60と、を備え、ストッパ60は、スクリュー軸38の軸方向に対する傾きを弾性的に規制する規制部材61を備えており、規制部材61は、インナーチューブ56の内周面に常時摺接されている。【選択図】図3
