Claims

[Claims for Utility Model Registration] (1) A center post as a fixed iron core, a plunger as a movable iron core that is arranged coaxially with the center post so as to be able to reciprocate, and a plunger that is arranged so as to surround the outer periphery of the center post. It is equipped with a coil that
In the solenoid, the shape of the suction portion of the plunger and the center post is a conical uneven shape that can be inserted into and removed from each other freely, and the inner peripheral shape of the conical recess of the suction portion of the plunger and the center post is an opening. a conical surface that follows the outer peripheral conical surface of the conical convex portion from the side toward the back;
A solenoid characterized in that it has a structure that includes, following the conical surface, a relief surface that has a larger inclination than the conical surface and forms a gap between the conical surface and the outer circumferential conical surface of the tip of the conical convex portion. (2) The solenoid according to claim 1, wherein the relief surface is a cylindrical surface.
