Claims

[Scope of utility model registration request]

A plastic crossbar that is rotatably provided, a movable contact that is rotatably supported by the crossbar via a rotation shaft, and when it comes into contact with the movable contact, the movable contact almost In the circuit breaker, the circuit breaker includes a fixed contact having parallel conductor portions, and a torsion coil spring supported by the cross bar and for applying contact pressure to urge the movable contact toward the fixed contact. The movable contact consists of a plurality of inner movable contact pieces and an outer movable contact piece disposed on both sides of the inner movable contact piece, and its shape is such that the flexible conductor connection part of the inner movable contact piece is connected to the outer movable contact piece. A circuit breaker characterized in that a load support hole portion of the outer movable contact piece into which a pin that engages with the torsion coil spring is inserted protrudes from and does not overlap with the inner movable contact piece.
