摘要： An actuator and a vehicle door opening/closing actuator are provided. The actuator includes a screw shaft (38) that is driven to rotate by a rotational force of a shaft (14) of a motor part (11); a nut member (58) that is fixed to an inner tube (56) and linked to the screw shaft (38) to move along the axial direction of the screw shaft along with rotation of the screw shaft; and a stopper (60) that is disposed at the other end (38b) of the screw shaft (38) on the side opposite to the motor part to prevent the nut member from coming off the screw shaft. The stopper (60) includes a regulating member (61) that elastically regulates inclination of the screw shaft (38) with respect to the axial direction. The regulating member (61) is constantly in sliding contact with the inner circumferential surface of the inner tube (56).
