A single rod is pivotally supported at the tip of the base rod via a support shaft, and a connecting shaft provided on the breaker body and extending from the base of the single rod are connected at a position displaced from the main shaft. A tension member is stretched between the connecting shaft at the tip of the provided arm,
The main pivot, the support shaft, and both connecting shafts at both ends of the tension member are arranged to form a parallelogram, and the tension member is connected to the shaft on the base side, the tip of the shaft, and the connecting shaft at the tip of the arm. It consists of a tension cable that connects the
The arm is characterized in that the base of the shaft is rotatably supported only around a horizontal connection axis, and a breakage preventer is provided at the base of the base of the base to prevent the distal end from bending diagonally upward. type circuit breaker.
