Similarly, the upper end of the apron 54 is fastened to the insert nut 55 which has been driven into a boss 53 formed in advance on the flange 52 of the bathtub by tightening a bolt 57, while the boss is also provided on the inner surface of the apron 54. The lower end of the stay 60 is connected to the apron 54 by fastening a bolt 57 to the insert nut 55 driven into the boss 54c.

In such a conventional structure, it is necessary to integrally form the thick boss portion 53 at the time of forming the bathtub 51. Since the boss portion 53 is thick, it takes a long time to cure.
There is a problem that the formability of the bathtub 51 is deteriorated. On the other hand, since the notch 56 needs to be formed on the apron 54 side as well, the tip of the notch 56 is formed when the apron 54 is formed or used. There is a problem that cracks K are easily generated. Further, when the bolt 57 is tightened, a force is applied in a direction in which the insert nut 55 is pulled out of the boss portion 53, so that the insert nut 55 is likely to come off, and the fixing of the apron 54 may become unstable.
Further, when the bathtub 51 is made of transparent artificial marble, when the flange portion 52 of the bathtub 51 is viewed from above, the shadow of the thick boss portion 53 is viewed from above. However, there is also a problem that appearance is deteriorated.

FIG. 10 shows a different conventional mounting structure. In FIG. 10, a fixing member 61 is bonded in advance to the lower surface of the flange portion 52, while FIG. As shown in FIG.
A through hole 62 is formed in a penetrating shape, a bolt 57 is passed through the through hole 62 from below, and the apron 54 is attached by tightening the bolt 57 to the fixing member 61. Also in the structure, it is necessary to form the through hole 62 in the apron 54 in advance, so that the apron 54 is easily cracked, and when the bolt 57 is tightened, a downward force is applied to the fixing member 61. In addition, this force causes the fixing member 61 to move the flange 5
Since the fixing member 61 acts in the direction in which the fixing member 61 is peeled off from the flange portion 52, the fixing member 61 may come off the flange portion 52.
