The lower portions of the pair of wind stop blocks 71 may be integrally connected by a plate 80, and a drain hole 81 may be formed in the plate 80.

That is, the windbreak member 70 may have a drainage portion whose upper surface is discontinuous in the longitudinal direction and whose discontinuous portion is continuous to the lower surface.

In the above embodiments, a special type of sliding sash for moving the inner and outer shoji 6, 7 up and down has been described, but the inner and outer lower rails are integrally provided on the lower frame to form the inner and outer shoji. It goes without saying that a normal pulling sash that opens and closes by moving 6 and 7 only in the in-plane direction may be used.

[0035]

According to the first aspect of the present invention, since the upper surface of the wind stop member is discontinuous in the longitudinal direction, a capillary tube is provided at the contact portion between the upper surface of the wind stop member and the lower surface of the outer frame of the shoji. Rainwater that has infiltrated due to the phenomenon will drip into the discontinuous portion and will not infiltrate into the room. Further, the wind stop member is formed with a drainage portion having a discontinuous portion continuous to the lower surface, and since the drainage portion is opened to the outside of the room by the drainage hole formed in the lower frame, the drainage portion is dropped onto the discontinuous portion. Rainwater is drained to the outside of the lower frame from the drain and drain holes. Therefore, since it is possible to reliably prevent rainwater from entering the indoor side from the interior / external shoji combination portion, a watertight structure for the arrangement portion having excellent watertightness is provided.

According to the second invention, rainwater dropped on the discontinuous portion of the windbreak member flows down into the hollow portion through the primary drainage hole,
Since the rainwater that has flowed down into the hollow portion flows out to the outdoor side from the secondary drain hole, the rainwater can be smoothly drained to the outdoor side.
