PROBLEM TO BE SOLVED: To provide a high-pressure gas container valve 10 in which damage in a screw part due to a galling phenomenon is inhibited. SOLUTION: A cylinder part 12 is formed in an upper side of a container valve body 11 of the high-pressure gas container valve 10, and a plug 13 is arranged to be screwed in the cylinder part 12. A gas flow passage 19, through which, for example, hydrogen chloride or the like flows, is formed on the lower side of the container valve body 11, and the gas flow passage 19 is opened/closed by turning the plug 13. In the high-pressure gas container valve 10, a male screw part 30 screwed in and contacting a high-pressure gas container 20 is aluminized, and then, is acid-treated. COPYRIGHT: (C)2011,JPO&INPIT
