Claims

[Scope of utility model registration request]

The proximal end of the iron core is fixed to a yoke attached to the electromagnetic coil, and a magnetic pole piece of a substantially L-shaped movable iron piece hinge-supported by the free end of the yoke is arranged to face the magnetic pole surface of the iron core, and the above-mentioned A hinge piece that elastically presses the movable iron piece against the outside surface of the yoke is provided protruding from a bent portion at one end of a hinge spring fixed to the outer surface of the yoke, and the other end of the hinge spring is pressed against the other end of the movable iron piece. In an electromagnetic relay in which the base of a movable iron piece is inserted through a through hole formed in the bent part of the hinge spring, the base of the movable iron piece is located near the magnetic pole piece and A protrusion is provided on the outer surface, and in the process of inserting the base of the movable iron piece through the through hole formed in the bent portion of the hinge spring, it slides into contact with the protrusion and the hinge piece of the hinge spring is inserted into the movable iron piece. An electromagnetic relay characterized in that a slide piece that is displaced in a direction away from the magnetic pole piece projects from the hinge spring.
