Claims

[Scope of utility model registration request]

A latch is rotatably supported by a pair of upright side plates, and when the movable contact is in the closed state, the latch is locked to a latch receiver to prevent rotation, and is released by a tripping command. In a circuit breaker opening/closing mechanism in which the movable contact is rotated until it hits a stopper pin inserted across the side plate and opens the movable contact, there is a gap between the end face of the side plate and the insertion hole of the stopper pin from the inner diameter of this hole. A small guide groove is formed, and a stopper pin having constricted portions at both ends is inserted into the insertion hole through the guide groove, and then slightly rotated to be held in the side plate. circuit breaker opening/closing mechanism.
