Zusammenfassung:	PROBLEM TO BE SOLVED: To efficiently perform a gas charge work. SOLUTION: In a first nozzle 11 for taking out gas of a first vessel valve 1 provided with a check valve 10 for response to a pressure, a check valve chamber 26, a check valve seat 27 and an outlet hole 28 are provided successively in a straight line shape. In an outer end part of a check member 29 inserted to this check valve chamber 26, a receiving protrusion 31 protruded in the outlet hole 28 is provided, the check member 29 is energized to the check valve seat 27 by a check spring 30. When a gas charge metal fitting 34 is connected to the first nozzle 11, an engaging protrusion 45 provided in a tip end of this metal fitting 34 separates the check member 29 from the check valve seat 27. The engaging protrusion 45 is constituted so as to prevent interfering with a peripheral wall 13a of an outlet path 13 of a second nozzle 12 when the gas charge metal fitting 34 is connected to the gas taking out second nozzle 12 of a second vessel valve 2 without having the check valve 10.
