PROBLEM TO BE SOLVED: To provide a gas cock in which blocking of gas circulation by an excess outflow protective valve can be appropriately performed.SOLUTION: A gas cock includes, in a tubular gas cock body 2 having a gas flow path 1 formed inside: a slide valve G movable in the axial direction of the gas cock body 2 between a closing position and an opening position; and an excess outflow protective valve H disposed upstream the slide valve G in the gas circulation direction of the gas flow path 1. The excess outflow protective valve H is configured to be movable from an initial position where the valve is separated from a fitting part H3c of a downstream member H3 disposed at a downstream side to allow the gas to circulate, to an operation position where the circulation of the gas is blocked while the valve is fitted to the fitting part H3c of the downstream member H3. |
