DESCRIPTION OF THE PREFERRED EMBODIMENTS In this embodiment, a mounting piece 2 protruding to the side of a sash 1 is brought into contact with an outer wall 3 from outside to fix the sash 1 and cover at least the outer edge of the mounting piece 2. The cover 4 is attached to the surface of the mounting piece 2 as described above, and the outer edge of the cover 4 projects outward from the mounting piece 2 at this time.
The watertight material 5 whose end is in contact with the watertight material 5 is directly attached, and the main body of the watertight material 5 is formed of an elastic material extending in the vertical direction. Hereinafter, this will be described in detail with reference to the drawings. FIG. 1 is a horizontal sectional view showing a watertight structure on the side of the sash, and FIG. 2 is a longitudinal sectional view showing a watertight structure on the lower part of the sash.

On the outer periphery of the sash 1, as described above, the mounting piece 2
Project outward. The mounting piece 2 comes into contact with the outer wall 3 and is fixed by screwing. The back surface of the mounting surface to be screwed is groove-shaped, and the groove is filled with a waterproof material 6 made of foam resin or the like to prevent water from entering from the screw hole. On the surface side of the mounting piece 2,
A rail 7 to which the cover 4 is fitted is formed. The rail 7 is formed on the surface of the mounting piece 2 on both sides and the lower side along the longitudinal direction of the mounting piece 2. The rail 7 is composed of a pair of opposed locking pieces formed along the mounting piece 2, and the fitting pieces 8 on the back surface of the cover 4 are engaged with the locking pieces.

A cover 4 attached to the side of the sash 1
Are located on the surface, a substantially flat surface plate 4a, an outer surface plate 4b located at the outer edge of the surface plate 4a and bent at a right angle from the surface plate 4a toward the indoor side, and an inner edge of the surface plate 4a, An inner side surface plate 4c bent at a right angle, a fitting piece 8 attached to the back surface of the front surface plate 4a, and a watertight material attachment groove 9 are provided. The cover 4 is made of the same aluminum alloy as the sash 1. The fitting piece 8 is composed of a pair of projecting pieces projecting from the rear surface of the surface plate 4a at right angles to the indoor direction. The watertight material mounting groove 9 is formed by bending the end of the side wall forming the groove inward of the groove to form a locking portion.

The watertight material 5 is formed of a pair of parallel flat elastic materials which are in contact with the outer wall 3 at substantially right angles. The bases of the two elastic members are integrally formed, and the protrusions having a T-shaped cross section of the bases are fitted into watertight material mounting grooves 9 formed on the back surface of the cover 4. In the present embodiment, rubber is used as the elastic material. However, the watertight material 5 is not limited to rubber, and may be made of another synthetic resin or the like. Watertight material 5
Is preferably such that it extends from the end of the watertight material mounting groove 9 formed on the back surface of the front plate 4a of the cover 4 to the outer wall 3 and further has a margin. The length of the watertight material 5 extending from the back surface of the surface plate 4a to the outer wall 3 makes the watertight material 5 substantially equal to the distance between the back surface of the cover 4 and the outer wall 3.
For example, as shown in FIG. 3, even when the exterior material has an uneven pattern and the outer wall 3 has unevenness, water tightness can be ensured. Further, in the present embodiment, since a pair of flat plates is used, even when one of the flat elastic members is twisted, water tightness is secured by the other.

Next, a watertight material 5 is attached to the lower cover 4 of the sash 1.
In the case of attaching, the items different from the case of attaching to the side will be described. Except for the shape of the cover 4, it is substantially the same as the above embodiment. On the surface of the fitting piece 8 of the cover 4, a groove 10 is formed in the horizontal direction.
Further, the lower end of the surface of the cover 4 hangs down and functions as a drainer by separating from the outer wall 3. The watertight material 5 is attached by fitting an end of the watertight material 5 into a watertight material mounting groove 9 formed on the back surface of the cover 4. The shape of the watertight material 5 is the same as that described above, except that it is mounted horizontally.
Rainwater that has entered through a gap between the lower end of the cover 4 and the outer wall 3 by blowing up or the like is stopped.
