Claims

[Claims for Utility Model Registration] (1) An iron core around which a coil is wound is arranged on a base, and is connected to one end of the iron core, and is connected to the other end of the iron core by going around the outside of the coil. In an electromagnet device that has a yoke facing nearby, and an armature that is pivotally supported by the yoke and can be moved into and out of the other end of the iron core, the armature is biased away from the iron core by a return spring. A retaining rib along the armature is protruded from the base, and the return spring is integrally extended from the retaining piece and a retaining piece inserted between the yoke and the retaining rib through an insertion hole formed near the pivot portion of the armature. The spring has a spring piece that urges the tip of the armature away from the iron core, and an engagement notch is formed on the surface of the holding rib that faces the yoke, and the holding piece has an engagement notch that urges the tip of the armature away from the iron core. An electromagnetic device that is formed with a cut-and-raised piece that engages with a notch to prevent the return spring from coming off. (2) The retaining piece of the return spring is provided with a locking piece that is arranged so as to hang over the opening edge on the tip side of the armature in the insertion hole to prevent the armature from coming off from the yoke. Scope of patent registration request No. 1
Electromagnetic device as described in section. (3) The electromagnet device according to claim 2, wherein the armature is arranged such that the holding piece near the locking piece is bent toward the base of the armature.
