It flows into the space part 51 in the inner space 54 and the space part 51 in the slope 3, and is quickly drained to the bathroom side from the drain port 12 on the end cap 4 bathroom side. Further, a gap 46 is formed between the tight material holding part 5 below the insertion part 6 of the end cap 4 and the bathroom floor surface 13, and the gap 46 can also be drained. The space 51 inside the slope 3 has a process in which water that has entered the dressing room side of the rising piece 10 on the lower frame 1 is drained to the bathroom side, and hot water overflows from the bathtub, causing water to flow on the lower frame 1 side. When a large amount of water is rushed, it has the function of temporarily storing water.

FIG. 10 shows another embodiment of the end cap 4. The end cap 4 has two cuts 47 formed in parallel on the upper wall 37 from the dressing room side to the bathroom side, and an elastic locking piece 48 for the slope engaging portion 23 of the lower frame 1 on the upper wall 37. Is formed. At the end of the elastic locking piece 48 on the dressing room side, a locking portion 49 that locks to the slope engaging portion 23 of the lower frame 1 is formed protruding upward. The structure of the attachment portion of the end cap 4 to the slope 3 is the same as in the embodiment described above.
FIG. 11 shows a procedure for attaching the slope cap 3 to the lower frame 1 using the end cap 4. First, as shown in FIG. Is pushed and deformed downward, and the slope 3 is moved horizontally from the bathroom side toward the dressing room side. Thereafter, when the finger that has been pressed is released, the elastic locking piece 48 is restored, and the locking portion 49 is locked to the slope engaging portion 23 of the lower frame rising piece 10 as shown in FIG. Is fixed to the lower frame 1. When the slope 3 is removed, the slope 3 may be moved horizontally to the bathroom side while the elastic locking piece 48 is pushed downward. Note that when the end cap 4 is used, the engaged portion 29 is not necessary for the slope 3. In this way, the slope 3 is not directly engaged with the rising piece 10 of the lower frame, but the end cap 4 can be engaged with the rising piece 10 so that the slope 3 can be attached to and detached from the rising piece 10. .

  FIG. 12 shows still another embodiment of the end cap 4, and the shape of the protruding portion 7 is different from that of FIG. 6. The protruding portion 7 extends separately from the insertion portion 6 in parallel with the tight material holding portion 5 next to the insertion portion 6, and a locking portion 8 formed to protrude laterally at the tip of the protruding portion 7 is a tight material. The holding part 5 is engaged with the notch 9 formed in the vertical wall 52 and the bottom wall 53 on the dressing room side.
