The tank structure includes a tank body formed in a tube shape with at least one corner inside the tank body, the tank body having openings at both end portions thereof, and a pair of end patch plates fixed into the openings to fluid-tightly block off the openings, respectively. The end patch plates are formed to have a thin-walled portion at a position thereof corresponding to the corner of the tank body. |
