  As in Patent Document 1, in a configuration in which a water-stopping material is provided on the joint between the sash and the outer wall disposed on the lower side of the sash, the water is stopped in the vertical direction (width direction of the joint) between the sash and the outer wall. In the case where the joint is sealed by compressing the material, the compressive force on the waterstop material changes because the distance between the sash and the outer wall varies in the vertical direction. If the compressive force with respect to a water stop material changes, the water stop performance of a water stop material will change. In particular, when the distance between the sash and the outer wall is larger than the assumed distance, the necessary compressive force for the water stop material cannot be obtained, and the water stop performance of the water stop material is deteriorated.

  The present invention has been made in consideration of the above-described facts, and an object of the present invention is to enable a water-stopping material to exhibit a required water-stopping performance even if the distance between the sash and the outer wall varies in the width direction of the joint.

  According to the second aspect, the first water-stopping material and the second water-stopping material are pressed against the first water-stopping material fixed to the sash by pressing the second water-stopping material fixed to the outer wall in the depth direction. Can be compressed in the depth direction. For this reason, a compression allowance can be enlarged compared with the case where it comprises with a single water stop material.

  According to a third aspect of the present invention, the first water-stopping material is fixed to the near side in the depth direction in the extending portion extending from the sash to the joint, and the second water-stopping material is the first water-stopping material. The first water-stopping material and the second water-stopping material are compressed by pressing against one water-stopping material from the near side in the depth direction.

  According to the 3rd aspect, an extension part supports the compression force which compresses a 1st water stop material from the near side of a depth direction. For this reason, a 1st water stop material can be favorably compressed compared with the case where there is no extension part.

  According to a fourth aspect of the present invention, the outer wall has a lower wall disposed on the lower side of the sash in a state of projecting to the outdoor side of the sash, and an outer wall of the sash in a state of projecting on the outdoor side of the sash. A side wall disposed on a side part side and a side part side of the lower wall, and having a vertical joint between the sash and the lower wall, and extending from the side part of the sash along the vertical joint. It is provided with a water-stopping material for vertical joints that is provided up to the side of the wall and that is disposed obliquely at the side of the lower wall so as to gradually shift to the outdoor side as it goes downward.
