The engaging portion 45. As shown in FIG. 3, the engaging portion 45 is a stepped portion formed by the inner peripheral surface of the opening 24 and the inner peripheral surface 38 of the sewage basin 23 when the adapter 22 is fitted into the opening 24. That is, it has a function of contacting the engaged portion 46 and positioning the adapter 22 in the cylinder direction (rightward in FIG. 3).

Further, as shown in FIG. 2, a display 50 indicating the size of the branch pipe 27 is provided on the funnel-shaped inclined surface 39 of the covering portion 31 at a position located on the bottom side of the sewage basin 23. The display 50 is provided by a conventionally known method, and may be formed as a convex portion or a concave portion on the inclined surface 39, for example. Furthermore, the display 50 may be drawn by corroding the surface of the inclined surface 39, or a label on which the display 50 is printed may be attached. The size of the branch pipe 27 refers to various standards including at least the nominal diameter of the branch pipe 27. These various standards refer to the outer diameter of the branch pipe 27 and the like. As shown in FIG. 4, the display 50 is formed at a position visible from the cleaning opening 26 of the sewage basin 23. In this embodiment, the nominal diameter “50” of the branch pipe 27 is provided as the display 50. Further, on the bottom surface of the sewage basin 23, the nominal diameters “100” and “100” of the short pipes 28 and the like fitted into the openings 24 and 25 of the sewage basin 23 are also displayed. “100” in the display of is visible from the cleaning opening 26.

Next, the operation of the adapter 22 will be described. As shown in FIG. 3, the adapter 22 is fitted and adhered to the opening 24 of the sewer 23, and the branch pipe 27 is fitted and adhered to the pipe connection hole formed by the inner peripheral surface 35 of the adapter 22. Thus, the opening 24 of the sewage basin 23 and the branch pipe 27 having a different diameter can be connected. When the adapter 22 is fitted into the opening 24 of the sewage basin 23, the engaging portion 45 of the adapter 22 engages with the engaged portion 46 provided in the sewage basin 23, and the cylinder of the adapter 22. Directional (rightward in FIG. 3) positioning is performed. Then, with the adapter 22 fitted in the opening 24 of the sewage basin 23, the covering portion 31 of the adapter 22 makes an annular contact between the engaging portion 45 of the adapter 22 and the engaged portion 46 of the sewage basin 23. It covers the contacts. Thus, for example, when the adapter 22 is fitted into the opening 24 of the sewage basin 23 in a state where sand, dust or the like is present in the gap between the engaging portion 45 and the engaged portion 46, The adapter 22 is mounted in a state in which there is a gap between the engaged portion 46 and the covered portion 31, which covers the gap, so that sand, dust, etc. in the sewage will be accumulated or caught in the gap. This can be prevented, and thus the reduction of the opening area of the branch pipe 27 can be prevented. Further, since the inclined surface 39 is formed into a gentle curved surface, when a brush or the like is inserted from the cleaning port 26 of the sewage basin 23 to clean the inside of the sewage basin 23 or the like, the brush or the like does not get caught. It can be inserted all the way in, and has the function of being easy to clean.

Since the size of the branch pipe 27 is displayed on the inclined surface 39 of the covering part 31 at a position located on the bottom side of the sewage basin 23, the nominal diameter of the branch pipe 27 is changed to the cleaning of the sewage basin 23. It can be confirmed through the mouth 26. As a result, unlike the prior art, it is not necessary to dig up the ground to see the nominal diameter displayed on the branch pipe 27, and the labor for replacing the damaged branch pipe 27 can be reduced. .

Further, since the guide surface 30 of the branch pipe 27 is provided at the opening end of the adapter 22 on the side where the branch pipe 27 is fitted and inserted, if the opening end is damaged, the guide surface 30 may be damaged. It is possible to prevent damage to the inner peripheral surface 35 of the adapter 22. As a result, even if the opening end portion of the adapter 22 is damaged, the end portion of the branch pipe 27 can be easily fitted into the inner peripheral surface 35 of the adapter 22. Since the end of the branch pipe 27 can be fitted and inserted into the inner peripheral surface 35 of the adapter 22 along the guide surface 30, the connection work can be simplified.

However, the adapter 22 of the above-described embodiment is formed so that the branch pipe 27 having a nominal diameter of “50” can be inserted into the pipe connection hole formed by the inner peripheral surface 35, and the inclined surface 39 is formed by “50”. , The branch diameter 27 is smaller than "100" and a branch pipe 27 other than "50", for example, a branch pipe 27 having a nominal diameter of "75" can be inserted as shown in FIG. Thus, the pipe connection hole can be formed, and the indication of “75” can be provided on the inclined surface 39.

In the above embodiment, an example was shown in which the adapter 22 was inserted into one opening 24 of the sewage basin 23 having two openings 24, 25 to which the connected pipes can be connected. As shown in FIG. 6, the adapter 22 is attached to the downwardly facing opening 49 in FIG. 6 of the substantially Y-shaped drainage basin 23 having three openings 47, 48, 49 to which connected pipes can be connected. Can be inserted. In this case, it is difficult to see the display from directly above the cleaning opening 26, but the display of the nominal diameter "75" can be seen from diagonally above the cleaning opening 26.

Further, although the main body 29 and the covering portion 31 are provided separately, they can be integrally molded. Further, although the hollow portion is provided between the inner peripheral wall 33 and the outer peripheral wall 32, the hollow portion may not be provided between them.

Further, the inner peripheral wall 33 is eccentrically provided with respect to the outer peripheral wall 32 of the main body 29, but the central axis of the inner peripheral wall 33 and the central axis of the outer peripheral wall 32 may be provided on the same axis. it can.

Although the display 50 showing the size of the branch pipe 27 is provided at one place, a plurality of displays 50 can be provided at a plurality of places around the entire circumference of the inclined surface 39. This is to make the display 50 easier to see from the cleaning opening 26.

Further, although the inclined surface 39 is provided inside the covering portion 31, the covered portion 31 can be a short cylindrical body without providing the inclined surface 39.
