Abstract:
This electromagnetic relay comprises a movable element (34), a movable yoke (36), a fixed yoke (37), a movable part (56), and a stopper part (9). The movable element has movable contacts (35A, 35B). The movable yoke is coupled to the movable element so as to reciprocate integrally with the movable element. The movable part includes a movable core (52) that is formed by a rigid body made of an inorganic magnetic material, and a shaft (53) that is formed by a rigid body made of an inorganic material. The fixed yoke is formed by a rigid body made of an inorganic magnetic material, and is disposed between the movable core and the movable yoke. The stopper part is integrally formed with one of the fixed yoke and the movable part while projecting toward the other one so as to come into contact with the other one when the movable part moves toward the fixed yoke.
