鋳鉄製の排水管２の一端を大径に形成してなる。
３は受口１内に挿入される鋳鉄製の排水管４の挿
入口である。(Embodiment) Hereinafter, an embodiment of the present invention will be described based on the drawings. In Figs. 1 to 4, 1 is a socket;
It is formed by forming one end of a cast iron drain pipe 2 with a large diameter.
3 is an insertion port for a cast iron drain pipe 4 inserted into the socket 1.
５は受口１と挿入口３との間に介在した環状の

内周端は挿入口３の外径より小径とされている。 Reference numeral 5 denotes an annular gasket interposed between the socket 1 and the insertion port 3, which is made of an elastic material such as rubber, and includes a flange 6 that comes into contact with the outer end surface of the socket 1, and a ring that extends from the flange 6 to the socket. It is integrally provided with a cylindrical part 7 projecting toward the proximal end of the socket 1 along the inner circumferential surface of the mouth 1, and an annular tongue piece 8 projecting obliquely inward from the flange part 6 side of the cylindrical part 7. Reference numeral 9 denotes an annular protrusion formed integrally with the cylindrical portion 7, which is tightly fitted into an annular groove 10 on the inner circumferential surface of the socket 1. Reference numeral 11 denotes an annular draining pleat provided on the flange 6, which integrally protrudes radially inward from the opening edge of the inner periphery of the flange 6, and the inner circumferential end of the pleat 11 extends outside the insertion opening 3. The diameter is smaller than the diameter.
従つて、受口１にパツキン５を内嵌し、その後

８で切断されている。 Reference numeral 15 denotes a flexible colored resin decorative cover body, which includes a cover part 16 that covers the entire outer surface of the flange part 6, and an insertion opening 3 from the inner edge of the cover part 16.
It is formed into an annular shape including a cylindrical insertion attachment part 17 which extends in the insertion direction and is inserted and held between the outer circumferential surface of the insertion port 3 and the inner circumferential surface of the pleat piece 11 in a sandwiched manner.
The decorative cover body 15 has a divided portion 1 at one end in the circumferential direction.
It is cut at 8.

付け状態が得られる。 Then, as shown in FIG. 4, with the gasket 5 interposed between the socket 1 and the insertion port 3, a decorative cover body 15 formed in the same color as each drain pipe 2, 4 is inserted into the insertion port. What is necessary is to fit the outer periphery of the drain pipe 4 on the third side, push the insertion attachment part 17 between the insertion opening 3 and the pleat piece 11, and bring the surface of the collar part 6 and the inner surface of the cover part 16 into contact. Then, as shown in Figure 1,
Due to the elastic force of the pleat piece 11, the insertion attachment part 17 is
An attached state in which the pleat piece 11 and the insertion opening 3 are held in a pinched manner is obtained.

きる。 As described above, the decorative cover body 15 having the same color as each of the drain pipes 2 and 4 is fitted onto the insertion port 3 side, and the insertion mounting portion 17 is attached to the pleat piece 11 and the insertion port 3 side.
The decorative cover body 15 can be attached by simply pushing it in between, and the attachment work can be easily performed. Furthermore, the flange part 6 is covered by the cover part 16, so there is no yellowing or peeling unlike paint, and the aesthetic appearance can be improved. Furthermore, even if dripping occurs on the flange 6 when the drain pipe 4 is top coated, the decorative cover body 1
5, it can be well covered. Further, unlike the conventional case, the annular groove 107 is not formed, and water accumulation can be effectively prevented. Furthermore, the decorative cover body 15 has a simple structure consisting of a cover part 16 and an insertion attachment part 17, and can be easily manufactured, and the decorative cover body 15 in various colors can be provided at low cost.
