Patent ID: 7750769

Claim:
An electromagnetic relay structured such that a base includes a fixed contact piece and a movable contact piece, and a movable contact point included in the movable contact piece is moved to contact and be separated from a fixed contact point included in the fixed contact piece, by driving the movable contact piece, wherein the movable contact piece includes: a terminal portion held in the base and partially protruding from the base; a first contact piece portion connected to the terminal portion and protruding from the base at a different position from the terminal portion; a bent portion connected to the first contact piece portion and changing a protruding direction gradually; and a second contact piece portion connected to the bent portion, extending in a different direction from a base portion, and provided with the movable contact point, wherein the base includes a deformation preventing portion that contacts at least one of the first contact piece portion and the bent portion before the first contact piece portion gets over an elastic region and reaches a plastic region in deforming, to prevent plastic deformation of the first contact piece portion, and wherein, when the electromagnetic relay is assembled, the movable contact piece has a first position in which the at least one of the first contact piece portion and the bent portion does not contact the deformation preventing portion, and a second position in which the at least one of the first contact piece portion and the bent portion contacts the deformation preventing portion.
