Abstract
An electromagnetic relay is structured such that a base includes a movable contact piece and a fixed contact piece. A movable contact point included in the movable contact piece is connected to and disconnected from a fixed contact point included in the fixed contact piece by operating the movable contact piece via a card. At least any one of the base and the card includes a guide portion for guiding the card in a freely reciprocating manner with respect to the base. The card includes a guide protruding portion and a pressing portion for pressing the movable contact piece to elastically deform the movable contact piece. The movable contact piece includes a guide portion in a side portion of the movable contact point. The guide portion includes a guide hole into which the guide protruding portion is inserted, a pressure receiving portion positioned at an opposite side to the movable contact point with respect to the guide hole and pressed by the pressing portion, and a reinforcing portion for preventing plastic deformation at a time of being pressed by the pressing portion. The guide hole maintains a non-contact state of the card during the reciprocating motion.
