ABSTRACT:
An electromagnetic relay has a movable block, hinge portions protruding from both sides of the movable block on an axis, having a wide connection portion and a shaft portion, a base block having common contact terminals disposed thereon, and an electromagnetic block mounted on the base block. The connection portions are welded to be integrated with the common contact terminals to provide welded portions. Based on excitation and non-excitation of the electromagnetic block, the movable block rotates, with the shaft portions as a rotation axis to open and close contacts. The welded portion is provided in an inside edge portion of the connection portion. A reference line connects a point of action located between the welded portion and the rotation axis, and a center of the welded portion. The reference line intersects a boundary between the connection portion and the welded portion, which are welded so as to be integrated.
