Claims

[Scope of Claim for Utility Model Registration] 1. A movable contact equipped with a movable contact base having spring properties to which a movable contact is fixed, and a fixed contact base disposed opposite to the movable contact and having a fixed contact fixed thereto. A mechanism for opening and closing the contacts of an earth leakage breaker consisting of a fixed contact element, a handle that is attached to the side plate with a shaft pin and rotates about this shaft pin, and a handle that rotates about the shaft pin as a fulcrum, and the movable contact that is rotated by the rotation of this handle. a push bar that drives the child; a connecting pin that is formed in a U shape and has U-shaped legs attached to the handle and the push bar to connect them; and a connecting pin that is fitted across the U-shaped legs of the coupling pin. A contact opening/closing mechanism for an earth leakage breaker, characterized in that it is equipped with a pin holding plate. 2. In the device according to claim 1, two holes are bored in the pin holding plate at the same pitch as the U-shaped legs of the connecting pin, and the U-shaped legs of the connecting pin are respectively inserted into these two holes. A contact opening/closing mechanism of an earth leakage breaker, characterized by being inserted. 3. A contact opening/closing mechanism for an earth leakage breaker according to claim 2, wherein the two holes have a diameter that allows each of the U-shaped legs of the connecting pin to fit without play.
