PROBLEM TO BE SOLVED: To provide a connecting structure of drain pipe joint which reduces drain noise sharply even if vibration is generated from the drain pipe joint. SOLUTION: An erect pipe 27 in a downstream part is fixed to a concrete slab 30 for separating an upper floor and a lower floor, and a packing 29 is interposed in an inner circumference of an upper receiving port 27a of the erect pipe 27 in the downstream part. A lower connecting part 25 is inserted into the inner circumferential side of the packing 29, and a drain pipe joint 20 is connected to the erect pipe 27 in the downstream part.
