<P>PROBLEM TO BE SOLVED: To provide a routing structure of hot water supply piping, dispensing with bisecting heat resistant pipes for hot water supply and an outer pipe at a wall part of a waterproof pan to carry out piping construction well, and eliminating a possibility of water leakage from a waterproof pan to the outside. <P>SOLUTION: A piping through-hole 8 is formed in a bottom wall part 13a of the waterproof pan 1 to distribute the heat resistant pipes 6, 6 inserted through the outer pipe 5 and extended from the water heater 3 side, up to the bathtub 2 side. A waterproof sleeve 7 for holding liquid-tightness between the outer peripheral surface of the outer pipe 5 and the inner peripheral surface of the through-hole 8 in the inserted state of the outer pipe 5 is mounted in the through-hole 8, and the waterproof sleeve 7 is provided with a cylindrical elastic bushing 76 for holding liquid-tightness between the outer peripheral surface of the outer pipe 5 and the waterproof sleeve 7. <P>COPYRIGHT: (C)2007,JPO&INPIT |
