第(2)項の回路遮断器。[Claims for Utility Model Registration] (1) A movable conductor having a contact point, a cross bar rotatably pivoting the movable conductor between an inner space and connected to an opening/closing mechanism, and an end portion of the movable conductor A movable conductor is normally biased between the spring support part of the crossbar and the spring support part of the crossbar in the direction in which the contacts close, and in the event of a short circuit, the movable conductor is forced to open due to electromagnetic repulsion and the contacts progress to open. The electromagnetic repulsion high-speed opening type has a suspended spring that biases the movable conductor in the direction in which the movable element opens when the moment force on the movable conductor in the direction in which the contact closes decreases or the movable element passes the dead center. 1. A circuit breaker having a contactor structure, wherein the spring is a torsion spring having a coil portion between arm portions, and the coil axis direction of the coil portion is arranged parallel to the rotation axis of the movable conductor. (2) The spring is a torsion spring having a coil portion between a long arm portion and a short arm portion, and the long arm side is supported on the spring support portion of the cross bar, and the short arm side is supported on the end of the movable conductor. The coil portion is supported on the formed spring bearing portion, and the coil portion is moved from between the spring bearing portion of the cross bar and the spring bearing portion of the movable conductor toward the rotation axis of the movable conductor, and the end portion around the spring bearing portion of the movable conductor. and the coil portion are biased so that they overlap, and the coil portion is placed in a position sandwiched between the end portion of the movable conductor and the inner wall of the crossbar with an appropriate gap. Circuit breaker according to claim (1) of patent registration. (3) The circuit breaker according to claims (1) and (2) of the utility model registration, wherein the spring is a single torsion spring. (4) The circuit breaker according to claims (1) and (2) of the utility model registration, characterized in that the spring is a double torsion spring.
