In the case of illustration, the upper speculative piece 2 is divided at the position outside the rail 3 closest to the room of the upper speculative piece 2, and the lower speculative piece 6 located below the upper speculative piece 2 is formed into the hollow portion 5. The lower frame 1 is divided into an outdoor lower frame material 101 and an indoor lower frame material 102 by dividing at the facing portion, and the upper prospective piece 2 of the outdoor lower frame material 101 is fitted to the indoor lower frame material 102. And the lower projection piece facing the hollow portion 5 of the outdoor lower frame member 101
61 is overlapped and connected to the lower projection piece 62 of the lower frame member 102 on the indoor side.

The upper prospective piece 2 on which the sliding door 8 is mounted has a horizontal or almost horizontal surface for the purpose of allowing the wheelchair to pass without any trouble. , 3, a rising piece 4 having a height equal to the height of the rail 3 is formed. The rising pieces 6 prevent the wheels from dropping between the rails 3, 3 by supporting the wheels between the adjacent rails 3, 3 while eliminating the drop of the wheels when the wheelchair passes over the lower frame 1.

The notch 41 is formed at the portion where the mating frames 9, 9 of the adjacent sliding doors 8, 8 overlap, and the baffle plate 7 is shown in FIGS.
As shown in FIG. 2, the wire is fitted in the notch 41, and is attached between the adjacent rails 3, 3 as shown in FIG. Notch
Since the wheel 41 is formed at the portion of the assembling frames 9, 9 off the path of the wheelchair, the wheel does not fall into the notch 41 when the wheelchair passes.

FIG. 1 shows a state in which the baffle plate 7 is accommodated in the notch 41, and in order to prevent the baffle plate 7 from falling out of the notch 41, the rising piece 4 left from the notch 41 is subjected to wind. The case where the stop plate 7 forms the engaged portion 42 that engages upward is shown. However, if the state where the wind stop plate 7 is restrained in the notch 41 is maintained regardless of the opening and closing of the sliding door 8, it is not always necessary. It is not necessary to form the engaged portion 42.

The windbreak plate 7 comprises a base 71 extending between the adjacent rails 3 on the upper projection piece 2 and a plurality of fin-shaped airtight members 72 projecting from the base 71. On the 3 side, as shown in FIG.
A rising piece 73 that abuts from below is formed on the upper part of the upper part. When the engaged portion 42 is formed on the rising piece 4, the base 71 is formed of a material that can be elastically deformed for attachment to and detachment from the notch 41.
