Claims

[Scope of utility model registration request]

(1) A handle, a link whose one end is pivoted to the handle, a lever whose center portion is pivoted to the other end of this link, and a presser plate which is pivoted to one end of this lever and can move up and down. and a rotatable trip lever having an engaging portion formed thereon, and a center portion of which is rotatably supported, and when one end is pressed by the other end of the lever by rotation of the handle. a latch whose other end engages with the engaging portion of the tripping rod; a spring that provides the latch with a rotational force that resists the pressure exerted by the other end of the lever; A circuit breaker characterized by having a movable contact that is displaced by the movement of the circuit breaker.

(2) The circuit breaker according to claim 1, which is provided with a roller at the other end of the lever. .
