As shown in FIG. 2, the hooking portion 26 causes a larger distance from the inner surface of the wall panel 10 than the total thickness of the rim portion 20 and the rim contact portion 34 of the rubber pad 32. Is formed. That is, the dimension b between the rim contact portion 34 of the rubber pad 32 and the inner surface of the wall panel 10 is formed to be larger than the thickness dimension a of the rim portion 20, whereby the rim portion 20 and the wall are formed. A predetermined gap is formed between the panel 10 and the panel 10. An elastic seal member 38 is inserted in the gap, and the elastic seal member 38 seals the gap.
The elastic sealing material 38 is made of a foamed elastic material, and is inserted in the gap in a state of being adhered to the rim portion 20 of the bathtub 14 in advance.

The support fitting 12 supports the bathtub 1

As described above, according to this embodiment, the bathtub 14, specifically, the rim portion 20 and the wall panel 10 are positioned with a gap therebetween and are vibration-insulated. Since the rubber pad 32 is interposed between the 12 as well, even if the bathtub 14 vibrates, the vibration of the bathtub 14 is suppressed from being transmitted to the wall panel 10,
Therefore, sound leakage to the outside of the bathroom is effectively suppressed.

Incidentally, FIG. 4 shows the result of measuring noise outside the bathroom when the bathtub 14 is supported according to this embodiment. However, in the figure, A shows the measurement result in the present embodiment, B shows the measurement result in a state where the bathtub 14 and the wall panel 10 are completely insulated without using the supporting metal fitting 12, and C shows the above-mentioned FIG. The measurement result in the case of the conventional support structure using the support fitting 200 is shown. From the figure, it can be seen that when the bathtub 14 is supported according to the present embodiment, the leakage of sound to the outside can be favorably suppressed particularly in the low frequency region.

In this example, the rim portion 20 and the wall panel 10 are sealed by the elastic sealing material 38 so that there is no water leakage, and the elastic sealing material 38 is made of an elastic material. It is also suppressed that vibration is transmitted from the bathtub 14 to the wall panel 10 via the elastic sealing material 38. Further, in this example, the bathtub 1 is attached to the upright hook portion 26.
Since the rim portion 20 of No. 4 is hooked, the displacement of the bathtub 14 in the horizontal direction is favorably prevented.

Further, according to this embodiment, since the load of the bathtub handrail portion 18 can be supported by the support fitting 12, the bathtub 14 is not deformed or deformed even when the bathtub user puts his weight on the handrail portion 18, for example. Bathtub 1 based on that deformation
4 can be prevented from shifting.

Moreover, since the rubber pad 32 is interposed between the placing portion 28 of the support fitting 12 and the handrail portion 18 of the bathtub 14, the vibration is transmitted from the handrail portion 18 to the support fitting 12. It can be prevented.

The embodiment of the present invention has been described in detail above, but this is merely an example, and the present invention can be configured in a form in which various changes are made without departing from the spirit of the present invention.
