ACTUATOR

PROBLEM TO BE SOLVED: To provide an actuator having a simple configuration and capable of assembling a lock pin in a member moving in the axial direction easily, preventing the lock pin from coming off the member moving in the axial direction, absorbing unevenness in dimensional precision of the lock pin and the other constituent parts, and reducing its cost. SOLUTION: This actuator is composed of the member moving in the axial direction capable of reciprocating and moving linearly and the lock pin connected with the member moving in the axial direction through a detachable connection mechanism provided in the member moving in the axial direction. The lock pin is provided with a non-bent part being extended in parallel with the member moving in the axial direction while they are mutually connected and a bent part having only one bent section for the non-bent part. The detachable connection mechanism is provided with a first supporting part for transmitting linear movement of the member moving in the axial direction to the bent part while they are mutually connected and a second supporting part for preventing the lock pin from coming off the detachable connection mechanism.
