Abstract:
A relay (100) for opening or closing a contact by an electromagnetic interaction, comprising:a coil (202) having a core (204) bent like an almost L shape; an armature (201) provided to generate a predetermined axial rock and displacement by said electromagnetic interaction with said coil (202) and serving to transmit said rock and displacement to a contact portion (10) through a card (104), thereby opening or closing a contact (103a); an engagement portion (201a) provided on said armature (201); and energizing means (205c), wherein said armature (201) is bent like an almost L shape such that outer peripheral surfaces of both ends thereof can abut on both end faces of said core, said engagement portion (201a) is provided by bending at least a part of an edge on one of sides of said armature (201) to be engaged with an edge portion (204c) on an end face at one of sides of said core (204), and said energizing means (205c) energizes said engagement portion (201a) of said armature (201) toward said edge portion (204c) of said core (204), thereby holding said armature (201) to be rocked and displaced by setting an engagement part of said engagement portion (201a) with said edge portion (204c) to be an axis.
