Abstract:
An actuator includes a motor, a rotation transmitting member, a reverse input preventing device, a converting device, and a rod. The motor includes a rotating shaft. The rotation transmitting member is configured to transmit rotation of the rotating shaft. The reverse input preventing device includes an input member and an output member. The reverse input preventing device is configured to prevent external force input to the output member from being transmitted to the input member. The converting device includes a nut that rotates according to the rotation of the output member. The converting device is configured to convert a rotary motion of the nut into a linear motion. The rod is configured to advance and retract according to the linear motion of the converting device. The input member and the rotation transmitting member are integrated. The output member and the nut are integrated.
