1. A tank structure that has a tank body for storing liquid and a control device for supplying or discharging the liquid to or from the tank body, the tank structure comprising:
- a flat upper member having a lower flat surface;
a flat lower member having an upper flat surface; and
a valve and coupling integrated unit,wherein the tank body has an upper flat surface and a lower flat surface which face the lower flat surface of the upper member and the upper flat surface of the lower member respectively,the tank body is held in sandwiched relation between the upper and lower members so that the upper and lower flat surfaces of the tank body are in contact with the lower flat surface of the upper member and the upper flat surface of the lower member respectively, andthe upper member and the lower member are wider in area than the upper and lower flat surfaces of the tank body,fastening members are provided in peripheral portions of the upper and lower members extending wider than the upper and lower flat surfaces of the tank body to fasten the upper member and the lower member between which the tank body is placed, andthe valve and coupling integrated unit includes;
a liquid supply coupling for allowing the liquid to flow in the tank body;
a liquid discharge coupling for allowing the liquid to flow out of the tank body;
a gas supply coupling for supplying gas to the tank body to discharge the liquid from the tank body;
a gas exhaust coupling for exhausting the gas from the tank body;
a liquid supply valve for controlling a flow rate of the liquid,a gas supply valve for controlling a flow rate of the gas to be supplied;
a gas exhaust valve for controlling a flow rate of the gas to be exhausted;
a liquid supply passage for providing communication between the liquid supply coupling and the tank body via the liquid supply valve; and
a gas passage for providing communication between the gas supply coupling and the tank body via the gas supply valve and providing communication between the gas exhaust coupling and the tank body via the gas exhaust valve.

Abstract
A tank structure comprises a tank body for storing liquid and control devices for supplying or discharging the liquid to or from the tank body. The tank structure further includes an upper exterior member having a lower flat surface and a lower exterior member having an upper flat surface. The tank body includes an upper and a lower flat surfaces facing the lower flat surface of the upper exterior member and the upper flat surface of the lower exterior member. The tank body is held in sandwiched between the upper and lower exterior members.
