With the shutter curtain 24 completely wound up from the state shown in the figure, the window portion is fully opened, and the seat plate 26 is landed on the bottom plate 18 in a state of being extended to the lower part, whereby the window portion is completely closed.

The shutter guide 16 is a pair of outer frames 28 fixed to both side edges of the opening of the building frame 1, and a guide rail frame 30 which is assembled inside the outer frame 28 and whose substantially U-shaped guide opening is directed inward. It consists of.

2 and 3 show a single component of the outer frame 28 and the guide rail frame 30, and FIG. 4 shows the assembling relationship between the outer frame 28 and the guide rail frame 30.
Both the outer frame 28 and the guide rail frame 30 are made of an extruded body made of an aluminum alloy.
The outer frame 28 shown in FIGS. 2 and 4 has a mounting base 281 fixed vertically inside the opening of the building frame 1 and an L and inverted L shape on one side of the mounting base 281. It is composed of an inner piece 282 integrally bent and formed, and an outer piece 283 bent in a straight line with the other side portion of the mounting base 281. The outer frame 28 is formed in a substantially deformed U shape by a metal plate in which the mounting base 281 and the inner piece 282 and the outer piece 283 have elasticity. Of these, the inner piece 282 is bent at a right angle to the base piece 281, while the outer piece 283 has an inclination angle of 91 degrees to the outside of the base piece 281, that is, an inclination angle of 89 degrees inward. It is bent and formed. Then, at the open end of the inner piece 282 (shown on the upper end side in FIG. 2), the screw fixing surface 282b is continuously formed in a rising shape at a position slightly retracted outward via the inclined portion 282a. ing. The screw fastening surface 282b of the inner piece 282 has a plate shape slightly thicker than the main body portion of the inner piece 282, and is formed so as to be polymerized with the inner mounting piece 303 of the guide rail frame 30 and screwed. Further, an engaging claw 283a having an L-shaped cross section is integrally formed inside the open end of the outer piece 283.

Next, in FIGS. 3 and 4, the guide rail frame 30 is open inward (indicated on the left end side in FIG. 3), and the guide 301 of the slat curtain having a substantially U-shaped cross section and the outer end of the guide 301 have a straight line. It is provided with an outer mounting piece 302 that is integrally extended and an inner mounting piece 303 that is integrally provided with a weight at a right angle to the inside of the open end of the guide 301.
