In addition, in the public basin 21 of this embodiment, the inflow port 25 is only curved upward, but as shown in FIG. 3, the middle of the curved portion of this inflow port 25 is shown. It is also possible to project the horizontal inlet part 25a from the part toward the side. By forming such a horizontal inlet portion 25a, when the drainage pipe 41 is buried and installed at a deep position, the drainage pipe 41 can be directly connected to the horizontal inlet portion 25a. In this case, the upward inlet port 25 is closed by a plug body or the like (not shown). When the drain pipe 41 is connected to the inflow port 25 and the horizontal inflow port 25a is not used, it has a curved tip portion that matches the shape of the inner peripheral surface of the curved portion of the inflow port 25. The plug body is fitted and the horizontal inlet portion 25a is closed.
