  However, in the wash bowl as the conventional example, the drainage passage for guiding the water flowing into the overflow hole 4 to the lower part of the drainage port 11 is formed in the side wall 14 of the bowl 1. It was difficult and expensive.

  On the other hand, in order to easily and inexpensively manufacture the structure of the wash bowl, as shown in FIG. 7, a drainage passage is not formed in the side wall 14 of the bowl 1 and penetrates the side wall 14 across the horizontal direction. There is a wash bowl of a type in which an overflow hole 4 is provided and a drainage member 7 is connected to the outer side of the overflow hole 4.

  In this wash bowl, an auxiliary metal fitting 8 for fixing the drainage member 7 on the outer side of the overflow hole 4 is mounted inside the overflow hole 4. For this reason, the thickness of the flange 81 of the auxiliary metal fitting 8 protrudes from the inside of the bowl 1, and there is a problem that the periphery of the auxiliary metal fitting 8 is easily soiled and is difficult to clean.

  Further, in this type of wash bowl, the overflow hole 4 and the drainage member 7 are connected in a substantially orthogonal state, so that drainage may not be performed smoothly, and drainage efficiency is not always good. Further, since the connecting portion is located below the back surface of the mounting surface portion 2 of the wash bowl, there is a problem that pride and dust are likely to accumulate on the outer surface of the drainage member 7.

  Further, in recent years, a wash bowl molded with a synthetic resin is provided. However, when the overflow hole 4 is formed on the side wall 14 of the bowl 1, the overflow hole 4 is formed on the wash bowl due to the mold. Therefore, the overflow hole 4 was formed in a separate process after the wash bowl was formed. Therefore, the manufacturing cost of the wash bowl is high.

  Moreover, when the overflow hole 4 is formed in the side wall of the wash bowl, the overflow hole is located in front of the washbasin, and the inside of the vicinity of the opening of the overflow hole 4 is exposed and its appearance is not preferable. There wasn't.
