Abstract
An electromagnetic relay has a base having an upper surface, an electromagnet block, formed by winding a coil around a spool with at least one end provided with a guard portion and inserting an iron core through a through hole of the spool, mounted on the upper surface of the base such that a shaft center of the iron core is parallel to the base, a movable contact, provided at a free end of a movable touch piece that rotates based on magnetization and demagnetization of the electromagnet block, that is brought into contact with or separated from a fixed contact, and a press-fitting portion that is press-fitted into a press-fitting hole provided at the edge of the outward surface of the guard portion along the shaft center of the iron core. The press-fitting portion extends to the lateral side from a fixed contact terminal that has the fixed contact.
