PROBLEM TO BE SOLVED: To provide a multi-tank type gas supply device capable of supplying gas without causing pressure loss when supplying gas from a gas supply device, because even if differences in internal pressures in a plurality of high-pressure tank occur, a reverse differential pressure does not act on an opening and closing valve.SOLUTION: A multi-gas tank type gas supply device 10 includes a plurality of high-pressure tanks 12, 14 connected in parallel to a gas filling 20 system and a gas supply system 22 via valve devices 16 and 18, each of which has gas filling paths, gas supply paths, and opening and closing valves provided in the gas supply paths. A valve device corresponding to at least a specific high-pressure tank by employing a high-pressure tank has the lowest internal pressure when supplying gas as the specific high-pressure tank 12 has a bypass path connecting the gas supply system and the high-pressure tank bypassing the opening and closing valve, and a check valve that is provided in the bypass path and permits only flow of gas from the gas supply system toward the high-pressure tank. |
