材を設けたことを特徴とする回路遮断器。 Bimetal that bends when overcurrent flows,
There is a trip rod that rotates due to the curvature of this bimetal, a catch that is released from engagement and rotates as the trip rod rotates, and a circuit that operates by the rotation of the catch. In the device, a substantially U-shaped concave bearing portion is provided on the frame so that the bottom thereof faces the bending direction of the bimetal, and the bearing portion is provided with a substantially U-shaped concave bearing portion such that the bottom portion thereof faces the bending direction of the bimetal. A circuit breaker comprising a biasing member that fits into a shaft portion and presses the rotating shaft portion toward the bottom of the bearing portion.
