る電磁リレー。[Scope of claim for utility model registration] An iron core wrapped with a coil, an armature that is energized to be released from the iron core when the coil is de-energized and is attracted to the iron core when the coil is energized, and an armature that is attracted to the iron core when the coil is energized. A movable member that responds to the pole, a movable contact provided on the movable member, a fixed contact that the movable contact makes contact with and separates from, a base on which each of these members is placed, and a base that is attached to the base so that the inside is airtight. In an electromagnetic relay having a case, the case is provided with a ventilation hole, and when the armature is released, the ventilation hole is closed to maintain airtightness, and when the armature is sucked, the ventilation hole is opened to maintain airtightness. An electromagnetic relay characterized in that the movable member is provided with an opening/closing member that releases the opening/closing member.
