Here, since the outdoor finding surface portion 424 of the lower stile 42 is arranged on the outdoor side of the entire lower frame 22 (particularly the outdoor end surface), the lower stile 42 has a function as a roof with respect to the lower frame 22. Therefore, it is possible to form a structure in which dust flying on the outdoor side does not easily enter between the lower stile 42 and the lower frame 22. Further, the outer rail portion 28 has a sand return structure formed by an upper piece portion 283 extending outward from the rising piece portion 281 and an outdoor piece portion 284 extending downward from the upper piece portion 283. This also makes it difficult for sand dust to enter between the lower stile 42 and the lower frame 22. Further, since the cover piece portion 27 of the upper frame 21 covers the outdoor upper edge portion of the upper stile 41, it is possible to prevent dust from accumulating on the upper stile 41. Even in such a dusty area, the sliding window 1 can be normally used. The dust accumulated on the lower frame 22 between the vertical frame 24 and the vertical frame 44 can be easily removed by sweeping out or sprinkling running water.

When it rains, rainwater is sprayed from the outdoor side onto the sliding window 1, but the infiltration of rainwater into the indoor side is suppressed by the above-mentioned water stop line.
Here, rainwater can infiltrate into the stile of the shoji 5 due to capillarity and kinetic energy. Since the rainwater that has entered the lower stile 52 collects to some extent on the sealing material 48, the weight of the rainwater that collects in this way generates a force that pushes back the rainwater that is about to enter between the lower stile 52 and the inner rail portion 29 from the outdoor side. it can. Further, the rainwater flowing down from the corner portion where the lower stile 52 and the vertical stile 54 are butted enters the indoor side region 35B between the outer rail portion 28 and the inner rail portion 29 along the arrow 11 shown in FIG. 2, and enters the lower frame 22. It is drained from the drain port 30 to the outdoor side by passing over the inner peripheral prospective surface portion 223. If there is a lot of rainfall and the amount of rainwater that enters the indoor side area 35B exceeds the amount of drainage from the drain port 30, and the rainwater level is about to exceed the outer rail portion 28, the rainwater in the indoor side area 35B is As shown by the arrow 12, the water is drained to the outdoor side beyond the outer rail portion 28.
