Claims

[Scope of utility model registration request]

A U-shaped yoke consisting of opposing side pieces and a connecting piece connecting these pieces; one end face is located inside the yoke, the other end face is located outside the yoke, and is located in the center of the connecting piece. A fixed core having a through hole that is fixed through the core and communicates both end faces thereof, a coil frame having an inner circumferential shell surrounding an outer circumferential shell on one end face side of the fixed core and extending coaxially with the fixed core, and an armature. It is supported by the inner circumferential body of the carp J shape so that its surface faces one end surface of the fixed iron core and can be freely displaced in the axial direction, and is attached in a direction away from the one end surface of the fixed iron core. The energized plunger, the fixed iron core and the coil wound around the coil frame so as to surround the plunger, and the side pieces of the yoke facing each other with the plunger in between and having the same polarity on the side facing the plunger. A permanent magnet is magnetically coupled to the fixed core, and is supported so as to be able to move freely in the axial direction by penetrating the through hole of the fixed iron core.
A magnetic retention type solenoid comprising a magnetic output rod whose base end is connected to the plunger.
