Summary:PROBLEM TO BE SOLVED: To obtain a movable contact device of a circuit breaker which is high in energization ability, which is downsized, and which is stable in contact resistance even though this is a shuntless energization mechanism. SOLUTION: Movable contacts 8 are installed in parallel in a plurality of numbers per one electrode, and between the plurality of numbers of the movable contacts 8, the inner diameter part 17a of an inclined coil ring spring 17 in which an inclined coil spring is formed in a ring state is positioned by a positioning means 8c and pinch-mounted, and the movable contactors 8 are pressed and slid to a connection conductor part 11b of a movable piece receiver 11 to receive the movable contactors 8 by the inclined coil ring spring 17.
