The outer end of the plate-shaped portion 41 in the left-right direction X abuts against the first bent wall portion 271 of the smoke deflector portion 27. The outer end of the plate-shaped portion 41 in the left-right direction X may be close to the first bent wall portion 271 of the smoke deflector portion 27.

[0034] As shown in FIG. 5, the first inclined wall portion 43 is provided on the outdoor side Y1 of the plate-shaped portion 41. The upper surface of the first inclined wall portion 43 is a surface that extends gradually inward in the left-right direction X as it extends downward. The upper surface of the first inclined wall portion 43 is inclined with respect to the vertical direction. The upper surface of the first inclined wall portion 43 faces diagonally upward. The lower end portion 431 of the first inclined wall portion 43 extends vertically downward.

[0035] The second inclined wall portion 44 is provided on the outdoor side Y1 of the plate-shaped portion 41. The second inclined wall portion 44 is arranged below the first inclined wall portion 43 and parallel to the first inclined wall portion 43. The upper surface of the second inclined wall portion 44 is a surface that extends gradually inward in the left-right direction X as it extends downward. The upper surface of the second inclined wall portion 44 is inclined with respect to the vertical direction. The upper surface of the second inclined wall portion 44 faces diagonally upward. The lower end portion 441 of the second inclined wall portion 44 faces vertically downward.

[0036] The plate-shaped portion 41 has a screw hole 46 formed therethrough in the indoor-outdoor direction Y. As shown in Fig. 3, a screw 47 is inserted into the screw hole 46 and screwed to the outdoor side plate portion 264 of the joint frame 24Y. The method of fixing the rainwater guide member 4 is not limited to screwing, but can also be suitably set by fitting, adhesive, or the like.

[0037] The plate-like portion 41 is positioned closer to the indoor side Y2 than the second bent wall portion 272 of the smoke deflector portion 27 of the joining frame 24Y of the inner shoji screen 2Y. In a plan view, the rainwater guide member 4 is positioned to overlap with the indoor side Y2 side portion of the first bent wall portion 251 of the smoke deflector portion 25 of the joining frame 24X of the outer shoji screen 2X and the second bent wall portion 252. For this reason, the indoor side Y2 side portion of the first bent wall portion 251 of the smoke deflector portion 25 and the second bent wall portion 252 are cut out so as not to interfere with the rainwater guide member 4.

[0038] As shown in Figure 4, an airtight material 33 is provided on the lower frame 12. The airtight material 33 extends in the left-right direction X. A windstop plate 36 is provided on the lower frame 12. An airtight piece 37 extending upward is provided on the windstop plate 36. The airtight piece 37 abuts against the surface 264a of the outdoor side plate portion 264 of the door frame 24Y. The airtight piece 37 abuts against the surface 264a of the outdoor side plate portion 264, thereby sealing the gap between the lower frame 12 and the inner shoji screen 2Y.

[0039] As shown in Figure 3, when the outer and inner shoji screens 2X and 2Y are closed, the outdoor area B indicated by the dots is the area located further outdoors than the outer and inner shoji screens 2X and 2Y. Airtight material 31 is provided to seal the gap between the outer and inner shoji screens 24X and 24Y, respectively. However, some rainwater seeps into the gap between the outer and inner shoji screens 24X and 24Y. Rainwater seeping through the gap between the outer and inner shoji screens 24X and 24Y hits the surface 264a of the outdoor side panel 264 of the outer and inner shoji screens 24Y. As shown by the two-dot chain line in Figure 4, rainwater C moves downward due to gravity toward the surface 264a of the outdoor side panel 264. The first inclined surface portion 412, the second inclined surface portion 422, the first inclined wall portion 43, and the second inclined wall portion 44 of the rainwater guide member 4 are gradually inclined downward toward the outdoor area B. When rainwater C hits the first horizontal surface portion 411 of the rainwater guide member 4, it is guided to the first inclined surface portion 412 and flows downward along the first inclined surface portion 412. When rainwater C hits the second horizontal surface portion 421 of the rainwater guide member 4, it is guided to the second inclined surface portion 422 and flows downward along the second inclined surface portion 422. When rainwater C hits the first inclined wall portion 43 and the second inclined wall portion 44, it is guided from the first inclined wall portion 43 to the lower end portion 431 and from the second inclined wall portion 44 to the lower end portion 441, respectively, and flows downward along the first inclined wall portion 43 and the second inclined wall portion 44. Once a path is created, rainwater C is pulled by surface tension and flows along the same path. The flowing rainwater C is guided to the outdoor area B and then discharged.

[0040] As shown by the two-dot chain line in Figure 4, an airtight line A is formed by the airtight material 32 and the airtight piece 37. The rainwater guide member 4 is arranged inside the airtight line A in the left-right direction X of the inner shoji screen 2Y. The rainwater guide member 4 is arranged closer to the outdoor area B than the airtight line A.

[0041] In the sliding window 100, rainwater C seeping into the gap between the sash frame 24X of the outer shoji screen 2X and the sash frame 24Y of the inner shoji screen 2Y strikes the surface 264a of the outdoor side panel 264 of the sash frame 24Y. Gravity causes the rainwater C to move downward along the surface 264a of the outdoor side panel 264. The rainwater C flows downward along the first horizontal surface 411, first inclined surface 412, second horizontal surface 421, second inclined surface 422, first inclined wall 43, and second inclined wall 44 of the rainwater guide member 4, and is guided to the outdoor area B and discharged. This prevents rainwater C from seeping indoors.

[0042] The rainwater guide member 4 is positioned closer to the outdoor area B than the airtight line A. At a position closer to the outdoor area B than the airtight line A, the rainwater C is guided toward the outdoor area B by the rainwater guide member 4. Since the infiltration of the rainwater C into the indoor side of the airtight line A is suppressed, the watertight performance can be improved.

[0043] The first inclined surface portion 412, the second inclined surface portion 422, the first inclined wall portion 43, and the second inclined wall portion 44 of the rainwater guide member 4 are inclined so that they gradually slope downward toward the outdoor area B. Rainwater C can be reliably guided downward toward the outdoor area B.

[0044] The first horizontal surface portion 411, the first inclined surface portion 412, the second horizontal surface portion 421, the second inclined surface portion 422, the first inclined wall portion 43, and the second inclined wall portion 44 that guide the rainwater C are provided on the rainwater guide member 4. There is no need to process the rainwater guide portion that guides the rainwater C directly on the joining frame 24Y or the joining frame 24X, etc., and since it is sufficient to fix the rainwater guide member 4, which is a separate member, to the joining frame 24Y, the processing and manufacturing of the joining frame 24Y can be easily carried out.

[0045] The rainwater guide member 4 is provided with a first horizontal surface portion 411 and a second horizontal surface portion 421 that lie along a horizontal plane. If the first horizontal surface portion 411 and the second horizontal surface portion 421 were not present and the first inclined surface portion 412 and the second inclined surface portion 422 were to extend upward as is, the cutout processing of the smoke deflector portion 25 of the interfering joint frame 24X would become large. By providing the first horizontal surface portion 411 and the second horizontal surface portion 421, the cutout processing of the smoke deflector portion 25 can be kept small and can be performed easily.

[0046] The outer end of the plate-like portion 41 of the rainwater guide member 4 in the left-right direction X abuts against the first bent wall portion 271 of the smoke deflector portion 27. The second bent wall portion 272 of the smoke deflector portion 27 covers a part of the rainwater guide member 4, so that the exposure of the rainwater guide member 4 when viewed from the outdoor side Y1 can be suppressed.
