ABSTRACT:
An electromagnetic relay makes it difficult for deformation due to impact force to easily occur even when bending work is applied to a contact plate. A coil block is put on a base and a moving contact plate and fixed contact plates are so juxtaposed as to oppose one another. The moving contact plate is constituted by a contact-fitting portion to which a moving contact is fixed, a push-in fixing portion which is pushed in and fixed to the base and from which terminal portions extend, and a connection portion for connecting the contact-fitting portion and the push-in fixing portion. The connection portion has a width smaller than those of the contact-fitting portion and the push-in fixing portion. A connection position between the push-in fixing portion and the connection portion is bent and a part of the contact-fitting portion is bent in such a fashion that the positions of the fixed contacts and the positions of the terminal portions are deviated with respect to an implanting direction of the fixed contact plates.
