PROBLEM TO BE SOLVED: To provide a surely non slip roll screen that when winding it up. SOLUTION: A roll screen R1 comprises a wind-up shaft 3 rotatably supported by brackets 2, 2 provided opposing each other at both ends of a frame 1, a screen S wound up round the wind-up shaft 3, and non slippage plates 4 fixed at both ends of the wind-up shaft 3 for guiding the screen S and preventing its slippage when it is wound up. The non slippage plates 4 are provided in the state where their circumferences 41 overhang around the wind-up shaft 3. The circumferences 41 of non slippage plates 4 are adjacent to the frame 1, and the distance between them and the frame 1 is smaller than the thickness of the screen S. COPYRIGHT: (C)2007,JPO&INPIT
