Claims

[Scope of utility model registration request]

A movable contact that opens and closes by rotating the handle,
A fixed contact that makes contact with and separates from the movable contact of the movable contact, a latch mechanism that latches the contact state between the movable contact and the fixed contact, and a current-carrying path that passes through the movable contact and the fixed contact, through which an overcurrent flows. A bimetal that heats up and deforms and pushes the free end of the contact piece of the latch mechanism in the direction of releasing the latch, thereby releasing the latch mechanism, and a spring bias that moves the movable contact in the direction of opening when the latch mechanism is released. In a circuit breaker equipped with a mechanism, a female screw hole for adjusting the pushing force between the contact piece of the latch mechanism and the free end of the bimetal is drilled in the contact piece or the free end, and the female screw hole is inserted into the contact piece or the free end. A circuit breaker comprising a recess that tapers in diameter along the screw insertion direction around the end of the hole on the screw insertion side, and the recess is filled with a screw fixing agent.
