PROBLEM TO BE SOLVED: To provide a slide-type movable contactor assembly of a circuit breaker capable of suppressing resistance and heat generation to a minimum by increasing the contact pressure with the movable contactor in an energized state. SOLUTION: The slide-type movable contactor assembly of a circuit breaker includes a movable contactor 1, capable of rotating about a rotation shaft 5, a connecting plate 2 that allows the rotation of the movable contactor 1 and provides an energizing path by coming into contact with the movable contactor 1, and a bimetal plate 6, that is arranged on the side surface of the connecting plate 2 and which bends toward the side of the connecting plate 2 to press the connecting plate 2 so that the contact pressure with the movable contactor 1 is increased higher, the higher the temperature during the period of energization increases.
