Abstract

PURPOSE:To reduce a load given to a hinge part when a shutter is folded and further, to easily position two shutters via the hinge part by folding the shutter double on the hinge part so as to be like a plate, and forming the hinge part so that its outside is thin and wide. CONSTITUTION:The shutter 01 is folded on the hinge part 04 so as to be like the plate. The shutter 01 is formed by connecting two vertically/integrally formed shutters 01a and 01b, via the hinge part 04 widely formed by a horn-like groove, inside, and folded by executing alignment so as to engage alignment parts 06b and 06a provided next to the hinge part 04. When the shutter 01 is folded like this, the hinge part 04 is bent so as to obtain comparatively large curvature, and the load given to the hinge part 4 is reduced. On the other hand, since the alignment parts 06a and 06b exist, two shutters 01a and 01b are not deviated. These shutters are used in such a manner that a shielding film passes between these two shutters.
