Claims

[Scope of utility model registration request]

A crossbar interlocking pin that transmits the opening/closing state of the circuit breaker is provided to protrude laterally from the circuit breaker main body side, and a rail groove member that engages with the interlocking pin is extracted at a guide hole provided on one end side. It is composed of an operation slide plate that is loosely fitted and supported by an operation slide shaft attached to a fixed frame member, and a rotatably supported operation transmission lever whose one end is connected to the other end of the operation slide plate. Opening/closing transmission mechanism of extraction type circuit breaker.
