<P>PROBLEM TO BE SOLVED: To provide a drainage connecting structure which not only ensures all of the ease and speediness of bathtub mounting work, the watertightness of both drain ports, and the function of absorbing mounting tolerance, but also protects a drain valve device, even if a means for lowering the height of a space between a bathtub bottom and a waterproof pan is employed in order to set the height of a straddled portion of the bathtub to a possible smallest value. <P>SOLUTION: According to the drainage connecting structure, a connecting joint 1 is connected to the drain port B2 of the waterproof pan B via an adjusting means 2 which can absorb the dimensional tolerance of the drain ports of the waterproof pan B and the bathtub A, respectively, in planar and vertical directions while ensuring the watertightness of both the drain ports at the time of mounting the bathtub A. <P>COPYRIGHT: (C)2003,JPO |
