It is set in consideration of the diameters of hot water supply / water supply piping and remedy equipment piping. In general, the hot water / water supply equipment pipes raised from the floor have a strong structure and are introduced from the first cylindrical parts 7A and 7B having a large diameter because of the low degree of freedom in the position of pipe connection. On the other hand, the hot water supply / water supply piping for the washing station branch and the facility piping for remedy have generally a flexible structure, and since there is a degree of freedom in pipe connection, the second cylindrical portions 10A, 10B, 10C having a small diameter, Introduced from 10D.

  The reason why the small diameter cylinder base 8 is provided under the second cylinder parts 10A, 10B, 10C, 10D is as follows. That is, when the small diameter cylinder base 8 is not provided under the second cylinders 10A, 10B, 10C, 10D, four circular shapes are shown on the right side of the pipe introduction member 1 in FIG. Piping must be introduced from directly under the part, and as a result, it is necessary to secure a large space for the piping. However, when the small-diameter cylinder base 8 is provided under the second cylinder parts 10A, 10B, 10C, and 10D, a space for piping is provided there, and it is arranged in a state close to the horizontal. The pipes can be easily introduced into the second cylinder parts 10A, 10B, 10C, and 10D, and the bent part of the pipes may be R. This is because it is close and easy to get water at the time of cleaning, so it is advantageous to provide a water stop line at a high position.

  A first cap 11 is fitted to each of the first cylindrical portions 7A and 7B, and a second cap 12 is fitted to each of the second cylindrical portions 10A, 10B, 10C, and 10D (in FIG. 1).

Are connected via the inclined portions 13A, 13B, 13C, and 13D, and are hollow. The second cap 12 also has large and small diameter portions 12A, 12B, and 12C whose diameter gradually decreases stepwise from the lower side to the upper side, and each diameter portion is continuously provided via the inclined portions 14A and 14B. It is hollow. The first cap 11 and the second cap 12 are made of a soft material. Examples of the soft material include ethylene propylene rubber (EPDM, EPM), nitrile rubber (NBR), fluorine rubber (FKM), silicone rubber (VMQ, FVMQ), styrene butadiene rubber (SBR), chloroprene rubber (CR), thermoplasticity. An elastomer (TPE), natural rubber (NR), or the like can be used. The first cap 11 and the second cap 12 can be used by being cut at an appropriate portion so as to be compatible with the diameter of the pipe that passes therethrough. As a result, pipe insertion holes 15 and 16 are opened above the first cap 11 and the second cap 12, respectively. In addition, the inclined portions 13A, 13B, 13C, 13D and the inclined portions 14A, 14B serve to prevent water accumulation by not providing horizontal portions in the first cap 11 and the second cap 12.
