。[Claims for Utility Model Registration] (1) An iron core around which an excitation coil is wound, a yoke magnetically connected in series to one end of this iron core,
an armature that is magnetically connected in series with the yoke and is attracted to the other end of the iron core in response to energization of the coil; a movable contact spring that is fixed to the armature; In an electromagnetic relay having a fixed contact provided at a position with which the movable contact spring comes into contact when the movable contact spring is attracted to the end, a recess is formed on the surface of the other end of the iron core, and a spherical elastic body is placed in the recess. The electromagnetic relay is characterized in that the spherical elastic body has a size such that when the armature is attracted and brought into close contact with the iron core, the spherical elastic body is elastically deformed and completely fits into the recess. (2) The electromagnetic relay according to claim 1, wherein the recessed portion has a conical shape.
