Claims

[Claims for Utility Model Registration] (1) An electromagnetic device having a plunger, a support frame that supports the electromagnet device, and a slider that is movably supported by the support frame and moves as the plunger is released; A release type electromagnetic device comprising a release spring that is engaged with the slider and always urges the plunger in the release direction, and when the plunger is released, the slider moves together with the plunger due to the spring force of the release spring. The release spring includes a coil portion attached to the support frame, and a U that is located in the center of the coil portion and engages with a spring engagement protrusion of the slider.
In the device consisting of a letter-shaped folded portion and both end portions extending to both ends of the coil portion and engaging with the support frame, a portion of the folded portion of the release spring that engages with the spring engaging protrusion is provided. 1. A release type electromagnetic device, characterized in that a flat portion is provided, and the folded portion of the release spring comes into contact with the spring engaging protrusion through the flat surface of the flat portion. (2) The release type electromagnetic device according to claim 1, wherein the flat part of the folded part of the release spring is formed by flat hammering.
