PROBLEM TO BE SOLVED: To operate a rolling screen in a single operation by providing projections in the both sides of a pull-out end of the rolling screen, providing guide grooves for guiding the vertical movement of the projections in both sides of an opening part, and providing permanent magnet members along the guide grooves. SOLUTION: A main body of a rolling screen 90 is detachably attached to a bracket 91 attached to the front part and the rear part of a ceiling frame 40, the screen 93 of the rolling screen 90 is rolled around a screen pipe 94, rod iron plates 96 are rolled in their pull-out ends 95, and the both ends of the iron plates 96 are projected from both edges of the screen 93 so as to constitute projections 96A. The projections 96A in the both sides are received by the inside in the front side of cart columns 30 so as to be integrally formed into guide grooves for guiding the vertical movement, and rail rubber permanent magnets 32 are arranged along the bottom face inside the guide grooves 31.
