PROBLEM TO BE SOLVED: To provide a gas discharging method capable of corresponding to impact and the like without discharging gas even when a collision occurs.SOLUTION: A high-pressure gas tank 10 is equipped with a tank valve 20 installed to a doom portion 12, and having a gas channel related to the supply/discharge gas in a tank; and a gas discharge valve 50 installed to the valve, having a fusible plug member 37 shifting a gas discharging path from the gas channel to a tank outside portion from a blocking state to an opening state with temperature rise, at a temperature sensitive projecting body 32, and discharging the gas in the tank to the outside. In the gas discharge valve 50, the temperature sensitive projecting body 32 is rotatably installed to the tank valve 20 so as to rotate and tilt the temperature sensitive projecting body 32 to a tank peripheral wall side of the doom portion 12, while keeping the blocking state of the gas discharge path. |
