An electromagnetic relay includes a movable element, a movable yoke, a fixed yoke, a movable section, and a stopper. The movable element includes a movable contact point. The movable yoke is connected to the movable element to move together with the movable element. The movable section includes a movable core made of an inorganic magnetic material and a shaft made of an inorganic material. The fixed yoke is made of an inorganic magnetic material and disposed between the movable core and the movable yoke. The stopper protrudes from either one of the fixed yoke or the movable section toward the other to contact with the other when the movable section moves toward the fixed yoke. The stopper is integrally formed with the either one of the fixed yoke or the movable section.

Electromagnetic relay

An electromagnetic relay includes a base frame including a main body supporting a fixed element, and a bottom plate having a plate thickness direction in an extending direction orthogonal to a central-axis line direction. An intermediate cover includes a covering plate facing a contact mechanism unit. An outer cover includes a top plate facing the bottom plate across the contact mechanism unit, and a first side plate extending from one end of the top plate and facing the covering plate. A first gap between the covering plate and the bottom plate in the extending direction and a second gap between the covering plate and the top plate in the extending direction are arranged to be substantially symmetric across the covering plate in the extending direction, the first gap and the second gap being on the first side plate.
