摘要

PROBLEM TO BE SOLVED: To lift/lower a screen along a guide member even when the screen is of a shape other than a rectangle.SOLUTION: A rolling screen includes: a support member fitted on a stationary surface; a winding pipe having both ends supported rotatably on the support member; a screen having an end connected to the winding pipe so as to be wound and unwound on the winding pipe; a weight bar connected to the other end of the screen; and a guide member provided near both side edges of the screen in a rotary axis direction of the winding pipe or at a center, for guiding the weight bar when the screen is wound or unwound. The guide member includes a first guide member for guiding the weight bar while coming in contact with an edge side of the weight bar, and a second guide member provided on the other edge side or at a center of the weight bar and guiding the weight bar at a position separated from the other edge side or the center in a front-rear direction of the screen, through an off-set member. At least a part of a width of the screen in the rotary axis direction is formed to be smaller than the other part.SELECTED DRAWING: Figure 2
