PROBLEM TO BE SOLVED: To provide a roll screen allowing a screen opening/closing bar to always move in parallel. SOLUTION: A bar 7 is fitted to the tip part of a screen wound onto a winding shaft, and both ends of the bar 7 are slidably inserted in guide grooves of a pair of guide rails 3a, 3b arranged in parallel. Two ropes 12a, 12b are inserted through the guide grooves of the guide rails 3a, 3b in a cross state so as to intersect inside the bar 7, and the ends of the respective ropes 12a, 12b are fixed at both ends of the guide rails 3a, 3b so as to prevent the bar 7 from inclining when the bar 7 for opening/closing the screen 6 moves.
