A dry water-stop gasket 10 according to an embodiment of the present invention is an annular gasket comprising a hollow seal portion 11 and a seal lip portion 12 integrally formed with the hollow seal portion 11. The hollow seal portion 11 is inserted along a joint space m which is formed between, for example, a rectangular opening sash 1 attached to a building and an outer wall panel 2 provided on the outer periphery thereof and also extends in a rectangular shape. The inner side surface 11a on the side of the opening sash 1 is made flat and fixed to the opening sash 1. The cross-sectional shape of the hollow seal portion 11 is such that the opening of the curved surface portion 11b having a substantially U-shape is closed by a flat inner side surface portion 11a. Then, the hollow seal portion 11 is sufficiently pressed in the direction of the arrow F shown in FIG. 4 by applying the outer wall panel 2 after the fixation, so that the water stopping effect is further enhanced. That is, the outer wall panel 2 is fixed where sufficient pressing is obtained. In addition, the fixing of the dry water-stop gasket 10 to the opening sash 1 is performed by attaching the flat inner side surface 11a to the opening sash 1 via the butyl tape 3 so that the installation is simple. In particular, no tools or jigs are required.

The seal lip portion 12 is a water return lip made of a rubber-like elastic material, and is a curved surface portion 11b of the hollow seal portion 11.
It is integrally formed with the hollow seal portion 11 by extrusion so as to extend substantially horizontally and protrude from the outside toward the outer wall panel 2. This seal lip portion 12
Is provided on the indoor side of the hollow seal portion 11, and when the outer wall panel 2 is constructed, the front end portion 12a abuts on the side end portion 2a of the outer wall panel 2 and the side end portion 2a and the curved surface portion 11b It plays a role in guiding the water that has entered from the middle of the room and preventing it from entering the room. That is, water is guided from the upper horizontal joint to the left and right vertical joints, and water is discharged to the outside from the drain panel 4 provided at the lower portion of the dry water-stop gasket 10 attached to the lower horizontal joint.
