PROBLEM TO BE SOLVED: To reduce noises which are made when a plunger is attracted. SOLUTION: An actuator 3 of resin is coupled to the tip of a reciprocated plunger 2 protruding partially from a solenoid 1, and the solenoid 1 controls the reciprocating movement of an object 4 through the intermediary of the actuator 3. The actuator 3 has two legs 5 on both its sides, and the legs 5 hit the sides of the solenoid 1 on an actuator side substantially at the same time when the plunger 2 is attracted by the solenoid 1. The two legs 5 are arranged along the diagonal lines of the nearly square part 6 of the end face of the solenoid 1 on an actuator side.
