PROBLEM TO BE SOLVED: To provide a drainage connecting pipe absorbing the dislocation occurring at the execution of a drainage apparatus without using a flexible pipe such as a bellows pipe. SOLUTION: This drainage connecting pipe 1 is used to connect the drainage apparatus to a riser S from an underfloor section. Bent sections 2 bent at a uniform angle are provided at two positions in the middle of the drainage connecting pipe 1, and a nearly S-shaped bent section 2 is provided on the drainage connecting pipe 1. The drainage connecting pipe 1 is formed flat to be wide in the direction perpendicular to the axis of the drainage connecting pipe 1. The drainage connecting pipe 1 is arranged at the positional relation that the central axes between both ends of the drainage connecting pipe 1 and between the bent sections 2 do not cross each other.
