Abstract
An electromagnetic relay in which an iron core 2 is fixed to a yoke 3, and one end of the yoke 3 is fixed by press-fitting to a base 4. The base 4 is formed with a yoke-receiving groove 4b into which tongue pieces 3e, 3e at one end of the yoke 3 are press-fitted, and a cutout groove 4c into which a head portion 2c of the iron core 2 is received. The yoke 3 is formed with a seal projection 3f disposed by insertion in an opening end of a cutout groove 4c of the base 4. This construction of the electromagnetic relay eliminates poor operation by preventing metal chips produced during assembly from adhering to electrical contacts of the relay.
