PURPOSE:To reduce an installation area by making a capacity of a gas storage tank smaller by utilizing an idle space in the tank formed by a tank reinforcing member for the space used for absorbing variation of an internal pressure of the tank consequent on the variation of used temperature. CONSTITUTION:An upper idle space 12a and a lower idle space 13a which are formed by an upper and lower reinforcing members 12 and 13 respectively in a tank 1 communicate with a gas storage tank 7A by pipes 14 and 15 and are used for a gas storage tank as a pressure avoiding space. By this constitution, it becomes possible to make a capacity of the gas storage tank smaller and accordingly to reduce an installation area. |
