PROBLEM TO BE SOLVED: To use the parts of gas cocks different in function in common and to reduce the manufacturing cost by forming a first butt section abutting on a stopper pawl at the ignition position and not abutting on it when a stopper is moved to a rotating action shaft side and a second butt section specifying the rotation terminal position of the rotating action shaft. SOLUTION: When a rotating action shaft 2 is rotated to the ignition position, a stopper pawl 62 on the outer periphery of a stopper 6 abuts on a first butt section 10b, and the further rotation of the stopper 6 is prohibited. when the stopper 6 is lifted, the stopper pawl 62 does not abut on the first butt section 10b formed at the abutting position of the stopper pawl 62 in the lowered state of the stopper 6, the rotating action shaft 2 is further rotated to reach the slow fire position, then the stopper pawl 62 abuts on a second butt section 10c. Most of parts can be used in common by newly assembling a cam plunger and a stopper in the cam plunger fitting space of a gas cock different in type from the gas cock that a coupling pawl 53 on the outer periphery of a cam plunger 5 is coupled with a coupling groove 61 on the inner periphery of the stopper 6 for a run-in action.
