PROBLEM TO BE SOLVED: To provide a supporting structure of a flange part in which safety can be enhanced by suppressing deformation at the flange part. SOLUTION: A tank B comprises the flange parts 2a, 2b provided at the opposite ends of a central container 1, first and second containers 3, 4 coupled with the flange parts 2a, 2b, and a supporting rod 40 provided between the flange parts 2a, 2b. Since the supporting rod 40 is provided, deformation of the flange part can be suppressed even when heat acts thereon. Since high temperature fluid in the tank B can be prevented from leakage, safety can be enhanced.
