And a bent portion 5a . This
As a result, the side portions of the shutter are reinforced, the sliding at the time of opening and closing is smooth, and dust and the like are prevented from entering the structure.

On the other hand, an attachment portion 6 for attaching a shutter to a structure is formed on the upper longitudinal end 2a of the base 2, which is the uppermost portion. Further, a horizontally long plate-shaped base 7 is continuously formed on the connecting portion 3 provided on the lower longitudinal end 2a of the base portion 2 which is the lowermost portion. At the center of the upper portion of the base 7, an operation unit 8 for opening and closing the shutter that is depressed inward is formed.

In the shutter having such a configuration, the opening and closing operation is performed by lifting and lowering the base 7 via the operation unit 8. The entrainment and pull-out work at the time of opening and closing is performed by opening the U-shaped connecting portion 3 by elastic deformation.
Closing or closing is easy and smooth.

As described above, according to the shutter of the present embodiment, since the whole is integrally formed by injection molding, the assembling work becomes unnecessary, and the shutter can be manufactured at low cost. In addition, the connecting portion 3 is particularly simple in structure, so that the winding and pulling-out operations at the time of opening and closing can be performed smoothly. Further, the shutter can be stably opened and closed by guiding the shutter to a rail-shaped shutter support provided on the frame of the structure, and the front of the structure provided with the shutter can be flush. In addition, the bases 2 can be firmly connected to each other by the connecting portions 3, and the work of winding and pulling out can be performed smoothly. And, since the base 7 is connected to the base 2 which is the lowermost portion of the shutter, and the operating portion which is depressed toward the inside of the shutter is formed on this base, it is not necessary to separately attach a handle or the like required for opening and closing the shutter. Accordingly, the shutter can be manufactured at a lower cost, and the shutter does not have a protruding portion when closed, so that the appearance can be improved.
