<p>Provided is an energy-saving electromagnetic relay excellent in impact resistance. To this end, in the electromagnetic relay, a movable iron core (34) is arranged to move up and down within a center hole (65) of an electromagnet unit (2) formed by winding a coil (60), and a contact switch is performed in such a manner that an upper end surface of the movable iron core (34) attaches to and detaches from a lower end surface of a fixed iron core (40) arranged in the center hole (65) according to magnetization and demagnetization of the electromagnet unit (2) and a movable contact (57) attaches to and detaches from a fixed contact (14) by a movable shaft (45) which reciprocates along with the movable iron core (34). Especially, a sliding portion (39) is arranged at a lower side of an annular groove portion (38) formed in an exterior circumferential surface of the movable iron core (34), the sliding portion (39) always faces an auxiliary yoke (74) having a cylindrical shape in a state in which the sliding portion (39) is disposed in the auxiliary yoke (74) provided in a yoke (70), and a height dimension of the sliding portion (39) is at least equal to or larger than a plate thickness dimension of the yoke (70).</p> |
