Claims

[Claims for Utility Model Registration] (1) A U-shaped yoke consisting of both leg parts and a connecting part that connects them to each other, which is wound around a bobbin so that its axis is almost perpendicular to the connecting part of the U-shaped yoke. a coil disposed between the two legs; a plunger movable in the axial direction within the bobbin; a release spring that constantly acts in a direction to project the plunger from the bobbin; a permanent magnet disposed on the connecting portion and constantly attracting the plunger into the bobbin overcoming the action of the release spring; and a transfer yoke disposed on the permanent magnet to face the inner end surface of the bobbin of the plunger. In the release type electromagnetic device, the release spring is configured to cause the plunger to protrude from the bobbin by canceling out the attractive force of the permanent magnet by energizing the coil, in which the connecting portion of the U-shaped yoke and the transfer A plate made of a non-magnetic material is disposed between the transfer yoke and the transfer yoke, and is secured to both side edges of the connection portion and the corresponding side edges of the transfer yoke, and has an opening into which the permanent magnet is fitted. A release type electromagnetic device characterized by: (2) Utility model registration claim 1, characterized in that the plate has locking pieces that lock on both side edges of the connection portion of the U-shaped yoke and the corresponding side edges of the transfer yoke. release type electromagnetic device.
