PURPOSE:To carry out the guiding of an underwater pump properly by making the distance between wires of the upper fixing device of an inverted U-type wire guiding unit narrower than that of the lower fixing parts, and by providing an opening on the antipump side of a wire-holder fixed to the underwater pump. CONSTITUTION:A projection 1b with a slope is formed on the upper side of inlet flange 1a of a discharge bent pipe 1, and the discharge bent pipe 1 itself is supported by a base 2 installed on the floor wall A of a liquid tank. On the other hand, a wire holder 4 is fixed on the upper part of discharge flange 3a of an underwater pump 3, and also this is provided with an opening 6 on the side opposite to guiding wires 5. Then, the lower ends of the guiding wires 5 are fixed to lower fixing parts 9, and the upper ends are fitted to the upper fixing device 10 provided with a tension bolt 13. In addition, the wire distance W at the upper fixing device 10 is made smaller than that W' at the lower fixing part 9. Thus, the fitting on and removal from the guiding wires 5 of wire holder 4 and the guiding of underwater pump 3 to the discharge bent pipe 1 can be properly performed.
