Claims

[Scope of utility model registration request]

A movable contact including a fixed contact, a movable contact that approaches and separates from the fixed contact, and a rod-shaped interlocking member that pivots the movable contact and is rotatably supported and responds to the on and off positions of the handle. A U-shaped contact holding plate that comes into elastic contact with the contact holding plate, an opening spring that elastically biases the contact holding plate, a latch link that responds to displacement of the bimetal, and a tip end that is connected to the latch link. A circuit breaker in which a trip link whose engaging/disengaging proximal end is linked to a handle and a handle that engages the trip link with the latch link when activated from an off position to an on position are housed in a housing, A stepped portion is provided on one side of both ends of the member, and a protrusion having a curved surface is provided on the inner surface of the housing, and the distance between the side surface of the stepped portion and the protruded portion of the housing is slightly larger than the width of the contact holding plate. The circuit breaker is set as follows.
