PROBLEM TO BE SOLVED: To provide drainage socket structure, in which a stool can be installed excellently even when the place of the extraction of a drain pipe is displaced. SOLUTION: A packing 2 is inserted into a drain pipe buried into a toilet floor face and fixed onto the floor face F, and mounted on the top face side in a manner that a drain inlet 8 for a stool can be inserted and connected. In the packing 2, the outer circumferential side of a central port 2, into which the drain inlet 8 is put, is supported at the upper end of a bottomed cylindrical member 3 capable of being moved in the horizontal direction, and an orifice hole 3c having a diameter smaller than the inside diameter of the drain inlet 8 is formed to the base of the bottomed cylindrical member 3 while a bellows section 2b capable of being expanded and contracted in the horizontal direction is formed on the outer circumferential side of the central port 3e of the packing 2 at that time.
