間に位置されて巻き取られる。2. Description of the Related Art A sheet shutter, in which a sheet is drawn out from a winding shaft to close an opening, and the sheet is wound around the winding shaft to open the opening, is particularly preferable. When a winding shaft having a small diameter is used in the large opening, the winding shaft is prevented from being bent at a plurality of positions in the longitudinal direction of the winding shaft in order to prevent the winding shaft from bending due to the weight of the sheet and its own weight. The support rollers are located opposite to each other and the sheet is positioned between the support roller and the winding shaft and wound.

発生することとなっていた（図１（ａ）参照）。However, at the time of winding the sheet,
The sheet is pushed by the supporting roller at a portion supported by the supporting roller to have a small winding diameter, and the sheet is supported by the supporting roller.
A difference in winding diameter occurs between a portion having no la and a sheet at a portion corresponding to the supporting roller is quickly wound to generate a wrinkle a (see FIG. 1 (a )reference).
