PROBLEM TO BE SOLVED: To provide an actuator capable of easily changing forward stroke of a piston rod.SOLUTION: In an actuator 25S of the invention, a piston rod 54S which may slide in a cylinder 26 includes a piston part 56 and a support rod part 54S extending from the piston part 56. The actuator 25S includes a lock mechanism R for restricting rearward movement of the piston rod 54S which occurs after the completion of forward movement. A holding part 68, on which an engagement member 77 forming the lock mechanism R is held, is disposed separated from the piston part 56 in a portion of the support rod part 54S which is located at the forward movement direction side of the piston part 56. |
