Claims

[Claims for Utility Model Registration] A hollow cylindrical solenoid body incorporating a coil, a center post fixed to one end of the hollow hole of the solenoid body, and a center post inserted from the other end of the hollow hole of the solenoid body. In the solenoid, the solenoid has a plunger that is magnetically attracted to the end face of the center post, and the solenoid body has a bearing portion that slides and guides the plunger in a reciprocating manner, wherein the gap between the sliding surface of the plunger and the bearing portion is is a damper gap of about 10 to 75 μm, and a space between a plunger and a center post of the solenoid body is a damper chamber communicating with the damper gap.
