PROBLEM TO BE SOLVED: To provide a structure that hardly produces abrasion powder, by improving a sliding part of a reset structure of an excessive flow-out prevention mechanism, in a gas cock with the built-in excessive flow-out prevention mechanism.SOLUTION: A slide cock 21b is urged in a closing direction within a plug part 2. A reset part 10 has a movement member 10a that moves integrally with the slide cock 21b and an excessive flow-out prevention valve 5 via interlocking means, and a stationary member 10b that is fixed within the plug part 2. The excessive flow-out prevention valve 5 has a reset body that protrudes to a downstream side from a case body 50 for accommodating a valve body and that is pushed into the case body 50 to return the valve body after an operation to an initial position. The stationary member 10b is positioned in close vicinity to the downstream side with respect to a protruding end of the reset body in a furthest protruding state. |
