Rainwater is prevented from entering the inside of the building from the end face of the sash, and high sealing performance can be maintained even when used in high-rise or super-high-rise buildings. Moreover, since the end surface of the sash is covered with the protrusion of the external sealing material, there is no contact between the end surface of the sash and the outside air, and therefore, the sash has a function of preventing discoloration or corrosion due to salt damage or the like. .

According to the outer wall member mounting structure of the sixth aspect of the present invention, the outer seal member has a cross-sectional area that is abruptly increased toward the inner peripheral portion at the intermediate portion between the outer peripheral portion and the inner peripheral portion. Since the step portion is formed to decrease, it is possible to increase the thickness of the portion where bending deformation easily occurs due to wind pressure or the like, while decreasing the thickness of the portion that contacts the outer wall material. As a result, it is possible to have a large proof stress against bending load due to wind pressure and the like, and it is possible to make the portion in contact with the outer wall material follow the deformation of the outer wall material. Therefore, it is possible to effectively prevent the intrusion of rainwater, and it is possible to maintain a high sealing property even when used in a high-rise or super high-rise building.
