PROBLEM TO BE SOLVED: To ensure the durability of pipes while suppressing an increase in pressure loss that occurs in pipes between high-pressure tanks.SOLUTION: A tank-mounting unit 10 comprises: fixed frames 13a and 13b provided on both sides of four high-pressure tanks, respectively; and a coupling frame 14c coupling the fixed frame 13a to the fixed frame 13b. Each of the fixing frames 13a and 13b includes a front frame portion that couples a first high-pressure tank to a second high-pressure tank; and a rear frame portion that couples a third high-pressure tank to a fourth high-pressure tank. The coupling frame 14c is provided on the rear frame portions closer to the second high-pressure tank than to the third high-pressure tank. A charging pipe 15 is connected to the third high-pressure tank from a charging port 20 along an upper portion of the coupling frame 14c, and a first pipe 16a is connected to the third high-pressure tank up to the fourth high-pressure tank. A second pipe 16b is connected to the fourth high-pressure tank up to the second high-pressure tank, and a third pipe 16c is connected to the second high-pressure tank up to the first high-pressure tank. |
