防止用突出片を形成したガス遮断器。[Claims for Utility Model Registration] An annular magnetic field generator disposed in an insulating gas atmosphere, an annular arc runner provided on one side of the magnetic field generator, and an annular arc runner disposed near a hollow portion of the arc runner. It includes a fixed contact and a movable contact that comes into contact with the fixed contact so as to be able to move toward and away from the fixed contact, and transfers the arc generated by the separation of both the contacts from the fixed contact to the arc runner, and In the gas circuit breaker configured to extinguish the arc by rotating at high speed outside the hollow part by electromagnetic force generated by the magnetic field of the magnetic field generator, the fixed contact is disposed on the near side of the fixed contact in the arc rotation direction of the arc runner. A gas circuit breaker, in which a protruding piece for arc spread prevention having the same potential as the arc runner is formed close to the arc runner.
