[Problems to be solved by the invention]
By the way, this type of mounting structure affects the production efficiency of the bathtub and the increase or decrease in time and labor when assembling the apron at the construction site. Therefore, the apron can be easily and easily reduced without reducing the production efficiency of the bathtub. It is desirable to be formed so that it can be installed and assembled on site. This type of structure is preferably formed so that the apron can be firmly attached so that the apron will not come off even after long-term use.
[0004]
However, in the conventional structure, the auxiliary member is formed in an L-shaped cross section as described above, and this auxiliary member is simply bonded to the back surface of the flange. Therefore, according to the conventional structure, the auxiliary member is placed at a predetermined position. Not only was it difficult to bond, but the auxiliary member was likely to fall off due to vibration or impact applied to the apron, and as a result, the apron could come off.
[0005]
In the conventional structure, as described above, since the auxiliary member has an L-shaped cross section, the opening lower surface (frontage) of the groove-like space is narrow. Therefore, in the case of the conventional structure, since it was difficult to insert and attach the upper part of the apron into the above-described space, the conventional structure has a problem that the apron mounting work and the assembling work cannot be simplified.
[0006]
The present invention has been proposed in view of such problems of the conventional structure.
Therefore, the technical problem of the present invention is that the auxiliary member can be easily installed, the bathtub can be efficiently produced and manufactured, the apron mounting state can be firmly and reliably maintained over a long period of time, and the apron mounting operation and assembly can be performed. It is an object of the present invention to provide an apron mounting structure for a bathtub that can be easily and quickly attached.
