Claims

[Claim for Utility Model Registration] A box-shaped base with an opening on the side, an iron core inserted into the center hole of a spool around which a coil is wound, and one protruding end serving as a magnetic pole, while the other protruding end an electromagnet portion having an end portion fixed to a vertical portion of a yoke having a substantially L-shaped cross section, and press-fitted from an opening of the box-shaped base in the axial direction of the iron core; It has a movable iron piece whose side corners are positioned at the horizontal tip of the yoke exposed from the opening of the box-shaped base, and a pair of arm parts bent and raised upwardly on both sides so as to face each other, and the pair of arms The elastic claw part is formed by cutting and raising the elastic claw part between the arms, and the engagement hole provided in the pair of arm parts is engaged with the protrusion protruding from the opposing outer surface of the base. In an electromagnetic relay comprising a hinge spring that presses an outer corner of the movable iron piece in the plate thickness direction and pivotally supports the movable iron piece with a hinge, a pair of tongue pieces facing each other at lower portions on both sides of the hinge spring. and a gap is provided between the hinge spring and the back surface of the vertical part of the movable iron piece by bringing the tongue piece into contact with the outer surface of the spool exposed from the opening of the base. electromagnetic relay.
