[0051] In the vertically sliding window 100 configured in this way, the flashing material 52 provided on the upper frame 11 contacts the frame-side contact surface 215a of the upper frame 21, thereby stopping water from entering. On the outdoor side Y1 of the frame-side contact surface 215a, a flashing recess 11a is formed by the outdoor frame plate portion 111, the upper wall portion 114, and the opposing wall portion 115 of the upper frame 11, which is recessed upward. Rainwater moves downward along the outdoor-facing surface 111a of the outdoor frame plate portion 111 of the upper frame 11 that faces the outdoors and falls. Even if a force acts on the rainwater to move towards the indoor side Y2 due to wind, etc., the flashing recess 11a is formed on the indoor side Y2 of the outdoor frame plate portion 111, and there is no wall portion that transmits horizontally from the outdoor frame plate portion 111 to the indoor side Y2, so the rainwater falls downward from the lower end portion 111d of the outdoor frame plate portion 111. Even if a strong wind blows and rainwater hits the surface of the opposing wall 115 facing the outside Y1, the rainwater will move downward along the opposing wall 115 and fall. Since the opposing wall 115 is positioned on the outside Y1 side of the position between the flashing material 52 and the frame side contact surface 215a, the rainwater that moves downward along the opposing wall 115 is blocked by the flashing material 52, preventing it from entering the building. This improves watertightness.

[0052] When the shoji screen 2 is installed with its own weight causing it to move slightly downward, the water-draining material 52 and the frame-side contact surface 215a of the upper frame 21, which are in contact in the indoor / outdoor direction Y, will come into contact at one of the positions in the vertical direction Z. Even when the shoji screen 2 is positioned slightly downward, watertightness can be ensured.

[0053] When the shoji screen 2 is installed with its own weight causing it to move slightly downward, the water-draining contact portion 52c of the water-draining material 52, which extends in the vertical direction Z, contacts the frame-side contact surface 215a of the upper frame 21 at any position in the vertical direction Z. This ensures watertightness even when the shoji screen 2 is positioned slightly downward.

[0054] If the shoji screen 2 is slightly positioned on the outdoor side Y1 due to construction errors, the water-draining contact portion 52c, which is elastically deformable in the indoor-outdoor direction Y, will be positioned with its lower end facing the outdoor side Y1 more than the state shown by the solid line in Figure 4, and will contact the frame-side contact surface 215a of the upper frame 21. If the shoji screen 2 is slightly positioned on the indoor side Y2, the water-draining contact portion 52c, which is elastically deformable in the indoor-outdoor direction Y, will be positioned with its lower end facing the indoor side Y2 more than the state shown by the solid line in Figure 4, and will contact the frame-side contact surface 215a of the upper frame 21. Watertightness can be ensured in response to the misalignment of the shoji screen 2 in the indoor-outdoor direction Y.

[0055] The water drain material 52 is provided on the upper frame 11. By providing a frame-side contact surface 215a on the upper frame 21, watertightness can be improved.

[0056] In the embodiment shown above, the flashing material 52 of the upper frame 11 and the frame-side contact surface 215a of the upper frame 21 are in contact in the indoor / outdoor direction Y, but this is not limited to this. The direction of contact between the flashing material and the contact surface can be set as appropriate. For example, the flashing material may be provided on the lower surface of the upper frame 11, and the flashing material may be in contact with the upper surface of the upper frame 21, in a configuration that contacts in the vertical direction Z.

[0057] In the embodiment shown above, the water draining contact portion 52c of the water draining material 52 extends in the vertical direction Z, but is not limited to this. The length of the water draining contact portion 52c in the vertical direction Z may be shorter.

[0058] Preferred embodiments of this disclosure have been described above with reference to the attached drawings, but it goes without saying that this disclosure is not limited to these examples.
