A fixing tool 11 is inserted from the hinge plate part 10 while being in contact with the outer skin 1, and is fixed to the band plate 12 via the outer skin 1. A fitting protrusion 5 is protruded from one of the opposing end surfaces of the panel bodies 4 that are vertically adjacent to each other.
A fitting recess 6 that can be freely fitted with the fitting protrusion 5 is provided on the other side. Here, at least one of the fitting protrusion 5 and the fitting recess 6 is provided with an elastic airtight material 7, and in the embodiment shown in the drawings, the fitting recess 6
An airtight material 7 is provided at. Rollers 13 are attached to both left and right ends of the panel body 4. In the embodiment shown in FIG. 6, a roller support portion 10a is provided on one hinge plate portion 10 of the hinge 8 located at the end, and a roller 13 is rotatably supported on this roller support portion 10a. Vertical rails 14 are provided on both sides of the opening of the building, and horizontal rails 15 are connected from the upper ends of the vertical rails 14 under the ceiling on the indoor side. In other words, the vertical rail 14 and the horizontal rail 15 constitute a substantially inverted L-shaped rail. The shutter 9 has each roller 13 fitted into the left and right rails so that it can run freely. When the shutter 9 is positioned on the vertical rail 14, the opening of the building is closed, and when the shutter 9 is moved and positioned on the horizontal rail, it closes the opening of the building. The opening is designed to be open. The shutter 9 is opened and closed by an opening and closing means 16. FIG. 3 shows an example of the opening/closing means 16. In this embodiment, the pulley 17
The lower end of the wound wire 18 is connected to the lowermost panel body 4, and this pulley 17 is rotated by a motor 21 to move the shutter 9 along the rail. In FIG. 3, reference numeral 19 denotes a coil spring wound around the shaft 20 of the pulley 17.
The motor 21 applies a spring force in the direction of pulling up and opening the shutter 9.
It serves to reduce the force required to pull up the shutter 9 due to its rotation. In this embodiment, a pulley 17, a wire 18, a coil spring 19,
An opening/closing means 16 is constituted by a shaft 20, a motor 21, and the like.
