Abstract
An electromagnetic relay includes a fixed contact portion including a fixed contact; a movable contact portion including a movable contact that contacts the fixed contact; and an electromagnetic device that operates the movable contact portion so that the movable contact contacts the fixed contact, and includes an armature that adsorbs to a magnetic core surface of the electromagnetic device and operates the movable contact portion by rotating with respect to a fulcrum, a hinge spring that pushes a part of the armature at an opposite side of the magnetic core surface while interposing the fulcrum therebetween so that the armature moves away from the magnetic core surface, and a fixed member that fixes an end portion of the hinge spring while having outside of a side surface of the armature as a fixed position, and wherein the fixed member is configured to fix the end portion of the hinge spring by moving the hinge spring from an upper side to a lower side of the armature, when attaching the hinge spring.
