PURPOSE: Disclosed is a charging valve for a vehicle gas fuel tank capable of rapidly responding to the change of a liquefied fuel level filled in the tank. CONSTITUTION: The charging valve for a vehicle gas fuel tank includes a fuel supply channel(10) for supplying a tank(2) with a fuel, a middle cavity(9) which is communicated with a fuel inlet channel(7), and an on-off means(12) for closing one of the channel(7,10). The fuel supply(10) is formed at a side part of the charging valve by a wall(9a). The on-off means(12) can move within the middle cavity(9). The on-off means(12) comprises a closing member(14) mounted in the middle cavity(9) and a membrane(13). This membrane(13) is disposed between the closing member(14) and the wall(9a) so that the closing member(14) is assembled with the wall(9a) in a sealing relation.
