2. Description of the Related Art A device disclosed in Japanese Utility Model Laid-Open No. 60-161279 is known as a device for connecting a plurality of shutters and continuously storing them in a door pocket or pulling out from the door pocket. As shown in FIG. 18, the invention is to rotate a pulley by connecting an endless rope c hung on a pulley arranged on an upper frame to a shutter b arranged at a position farthest from a door pocket a. The sliding door b is moved together with the moving rope, and the other sliding doors b are pulled by the sliding door b and pulled out from the door bag a, or pushed and stored in the door bag a.

Problems to be Solved by the Invention In the above invention, since the shutters b that move together with the rope c push the other shutters b to store them in the door bag a, the shutters b are pushed inwardly into the back of the door bag a. The side end of b is a flat tapered surface d, and it is pushed into the back of the door pocket a by sliding contact with the side ends of the adjacent shutters b.

Therefore, since the adjacent tapered shutter-side end faces d, d face each other, rainwater easily blows into the room through the gap between the shutters b, b. Further, since the rope c is connected only to the leading shutter door b and the shutter door b pulls the other shutter door b, when the shutter door b is pulled out, a gap due to the slack of the rope c is generated between the adjacent shutter doors b and b. As a result, the above-mentioned problems such as the blowing of rainwater become more serious.

Further, when storing the shutters b, the rear shutters b push the stored shutters to the outside so as to push them away, so that the shutters b, b may be damaged or deformed due to collision between them. .
