Claims

[Scope of utility model registration request]

An erectable operating handle is installed between the cover and the handle arm, a knob portion of the erectable operating handle projects outward from a through hole in the cover, and the erectable operating handle is operated by the knob portion. In a circuit breaker that operates a toggle link mechanism via a handle arm to open and close contacts, a fitting groove is formed around the through hole on the inner surface of the cover, and a ring made of an elastic body is inserted into the fitting groove. A circuit breaker characterized in that the ring is fitted and press-contacted to the upper surface of the collar of the tiltable operating handle.
