Claims

[Scope of utility model registration request]

Connecting holes provided at opposing positions of the U-shaped reinforcing member attached to the upper surface of the movable contact and connecting holes provided at mutually opposing positions of the inverted U-shaped holder of the movable contact, The movable contact is connected by passing through a connecting pin of the book so that the movable contact can rotate around the connecting pin, and the rotating operation of the holder causes the movable contact to perform an opening/closing operation between the contacts. In the contact portion of the circuit breaker, the connecting hole of the reinforcing member is made into a long hole in the direction of the rotational force of the holder, and the connecting pin has a plate-shaped fulcrum member perpendicular to the connecting pin in the center part. so that the peripheral end of the fulcrum member abuts the center portion of the reinforcing member at least in the state of contact between the contact points, and further, an opposite side having the connecting hole on both sides of the fulcrum member and the reinforcing member A spring is provided between each surface, and the spring holds the fulcrum member at the center of the reinforcing member, so that when the contact is in contact, the rotational movement of the holder is caused by the connecting pin. A contact portion of a circuit breaker, characterized in that the signal is transmitted to the reinforcing member via the fulcrum member attached to the fulcrum member.
