This airtight member 17 is made of hard parts up to the middle part of the mounting part 18, the base piece 21 protruding from the mounting part 18, and the on-off valve 20 protruding from the base piece 21, and other airtight parts. 1
9 and the tip side of the on-off valve 20 are made soft, and the installation is done using part 18.
It is possible to install the device firmly without detachment due to hardening of the side, and by making the airtight part 19 and the on-off valve 20 soft, it is possible to make close contact with the shoji 10 and smooth the valve action. It has the above effect.

22 is a screen fitted into the indoor side of window frame A. Reference numeral 23 designates a draining plate provided at the lower part of the window frame A on the outdoor side, and reference numeral 24 designates picture frame materials arranged in parallel on the indoor side of the window frame A.

In addition, in some cases, a stopper part 25 of the on-off valve 20 of the water return wall 5 in the present invention is provided at the abutting part, and an air-tight part 19 of the air-tight member 17 attached to the protrusion 7 may be provided.
is composed of a hollow first airtight part (a) and a second airtight part (a) located above the first airtight part (a) and protruding at an interval that prevents rainwater from seeping in due to a standing capillary phenomenon. There is also.

One embodiment of the condensation water treatment device for a window according to the present invention is configured as described above, so for example, when the dew condensation water treatment device of the present invention is applied to a casement window shown in each drawing and the condensation water is discharged, First, a pair of formwork members 3 and 4 are placed on both left and right ends of the lower frame member 1 and upper frame member 2 to assemble a rectangular window frame A, and then the window frame A is fitted into the opening of the building. After attaching the butterfly 16 so that the shoji 10 can be opened freely, the airtight member 17 is fitted to the protrusion 7 of the lower frame material 1, and the opening/closing valve 20 is placed on the ice return wall 5 of the lower frame material 1. In addition to being located near the outer surface, the airtight member 17
The lower part of the shoji 10 can be brought into contact with the airtight part 19 of the window frame A to maintain airtightness between the lower frame material 1 and the shoji 10. Or shoji 1
0, and is then discharged outdoors through the condensation drain 8. However, during strong winds, the on-off valve 20 of the airtight member 17 comes into contact with the outer surface of the water return wall 5, reducing the wind pressure. This prevents the backflow of condensed water and rainwater from the dew condensation drain port 8.

Also, a stopper part 25 of the on-off valve 20 is provided on the outer surface of the water return wall 5.
If the on-off valve 2 in the airtight member 17 is provided with
