PROBLEM TO BE SOLVED: To provide a piping structure between tank and pump being a simple constitution in which the number of parts is less. SOLUTION: The piping structure 34 is provided with a cylindrical liquid outlet 36 formed on the side wall part 14 of a chemical tank 12 in a power atomizer 10 and outwardly projected; a first hose 38 of which one end 40 is attached to a suction port 32 such that it surrounds the suction port 32 of a pump 20 and the other end 42 extends from the liquid outlet into the tank; and a second hose 44 of which one end is attached to the suction port so as to clamp one end 40 of the first hose between the suction port of the pump with it and the other end 48 is attached to the liquid output so as to surround the liquid outlet. In such the piping structure, only two hoses 38, 44 are basically required as a part and assembling may be carried out from the outside of the tank. The structure is a simple constitution.
