Abstract
An electromagnetic relay includes a first movable contact piece, a moving member, a coil, and a movable iron core. The movable iron core is connected to the moving member and is configured to move by a magnetic force generated by the coil. The moving member is made of an electrical insulator. The moving member includes a support portion and a connecting portion. The support portion holds a first movable contact piece. The connecting portion is connected to the movable iron core. The connecting portion includes a locking groove and a locking projection. An end of the movable iron core is disposed in the locking groove. The locking projection presses the end of the movable iron core in the locking groove. The locking projection extends in a support direction perpendicular to a moving direction of the moving member.
