用の操作装置。[Claims for Utility Model Registration] The closing cam is fixed to a rotating shaft that is interlocked with the drive means through a one-way clutch, and the holding plate for accumulating the closing spring is separated from the rotating shaft of the closing cam. An operating device for closing a circuit breaker, in which an arm whose one end is pushed out by a closing cam is attached to an operating shaft that is connected to a position via a rod and rotates to close or shut off the circuit breaker. A rotatable stopper is provided near the cam, and a buffer means for stopping the rotation of the stopper and a return spring that biases the stopper toward the buffer means are provided. Immediately before the direction of rotation changes, the stopper is rotated toward the side opposite to the shock absorbing means, and the charge cam is moved over the stopper, and after the direction of rotation is changed, the charge cam reverses and presses the shock absorbing means through the stopper. 1. An operating device for closing a circuit breaker, characterized in that a protrusion that engages with the tip of a stopper is formed at a position apart from the rotation axis.
