A side wall 131 that is bent upward and stands up is formed on a side portion of the bottom plate 121 near the bathroom 1.
Through holes 132 are formed in the side wall 131, and the bottom plate 12
The water above 1 can be discharged into the lower frame drainage groove 11 of the lower frame 10. In the fitting groove 133 formed between the lower surface of the bottom plate 121 and the inner surface of the support piece 122, the connecting piece 101 of the lower frame body 14 and the connecting packing 99 fitted to the connecting piece 101 are provided. Fit in. In this state, the upper part of the connecting packing 99 elastically abuts the lower surface of the bottom plate 121 to achieve watertightness over the entire length of the connecting packing 99 in the longitudinal direction.

A ridge 134 is integrally formed on the side wall 131 of the gutter body 23 on the bathroom 1 side, and the ridge 134 and the supporting portion 129 detachably support the gutter body louver 25. It Further, the upper end of the side wall 131 on the bathroom 1 side is fitted under the pressing part 111 of the lower frame body 14 to prevent upward lifting, and the gap between the side wall 131 and the rising part 109 is upward. It prevents the water from entering and prevents the intrusion of water.

Moreover, since the lower frame body 14 and the gutter body 23 can be separately manufactured and connected on site, the gutter body 23
Even when the gutter body sock 25 is not used, only the lower frame 10 can be used. Further, the upper frame 4 of the frame body 4
0 and the vertical frames 38 and 39 may be existing ones to connect the lower frame 10 of this embodiment, the gutter body 23, and the gutter body sprue 25, so that there is little structural change. Therefore, it is possible to realize a highly versatile lower frame drainage structure.

The present invention can be suitably implemented not only in connection with the lower frame of the frame body that holds the top-hanging folding door 3, but also in the frame body that holds the sliding door or the opening door.
