器。 A tripping mechanism that operates in response to the current flowing through the main circuit rotates a trip rod to cause the switchgear to perform a tripping operation, and the tripping mechanism is housed in a case together with the trip rod. A recess is formed in the inner surface of the case, and the rotation shaft of the trip rod is inserted into the recess, and the outer surface of the rotation shaft is on the side in the direction of pressing by the spring member for returning the trip rod. A support recess that becomes narrower toward the back is formed on either one of the inner surfaces of the case facing the outer surface, and a support protrusion that is inserted into the support recess is protruded from the other side. 1. A circuit disconnector characterized in that the rotating shaft is rotatably supported by contact between the tip of the convex portion and the bottom of the support recess.
