A Cylinder Valve 1 includes a Residual pressure Valve mechanism 100 located in a Residual pressure Valve mechanism insertion space 404 formed in a flow path 60. The Residual 5 pressure Valve mechanism 100 includes a valve 120 that is located in the Residual pressure Valve mechanism insertion space 404 so as to freely advance or retract to a valve close position or a valve open position and retracts toward the valve open position by a pressure of gas G flowing in the flow path 10 60; a forward convex portion 127 located at a tip of the valve 120; a coil spring 160 that urges the valve 120 in a direction in which the valve 120 advances from the valve open position toward the valve close position; and a seal seat 110 and a pressing portion 135 that retain the O-ring 150 while exposing 15 a contact permission portion 151 that allows the forward convex portion 127 to be in contact therewith. The seal seat 110 and the pressing portion 135 are secured to an outlet 40. |
