[origin: EP2654064A1] A compact and high-performance circuit breaker in which the force transfer efficiency of a switching mechanism unit is high is obtained. A circuit breaker according to the present invention has a link rotor engaged with a roller provided on the shaft of a rotor that holds a movable contactor; in the circuit breaker, when pivoting on the other end thereof due to the travel of a second link, the link rotor makes an engagement portion depress the roller while pivoting the roller so as to pivot the rotor, and a movable contact fixed to the movable contactor is made to make contact with or part from a fixed contact.
