Claims (1)

[Scope of utility model registration request] In a circuit breaker that is opened by releasing the retaining part that holds the main circuit in the closed state, the frame supporting the interrupting mechanism is biased upward by a spring, and the frame slides. A push button that fits in the groove and slides up and down and has a hook part, and further fits in the long groove of the frame so as to slide up and down and swing from side to side, and engages with the hook part. Accordingly, an oscillator is provided with a stepped portion forming the engaging portion, and further provided with a protrusion that engages with the movable contact plate described below; a movable contact plate made of an elastic metal plate having a self-biasing force weaker than a spring that always biases the push button in a direction to open the main circuit; A breaking mechanism for a circuit breaker comprising: a stator inserted into the push button and engaged with the push button to prevent the push button from coming off upward;
