PROBLEM TO BE SOLVED: To provide a roll screen device capable of adjusting the size of a space between a screen and a window and simplifying its structure. SOLUTION: The roll screen device is constituted by mounting the screen 10 in a windable and deliverable manner to a part extended along an upper frame 4 of the window 3 on the outdoor side of an external wall 1 of a building, and providing the screen 10 with a bottom bar 13. A first long-sized receiving member 20 and a second short-sized receiving member 21 are mounted to a projecting part 5a of a lower frame 5 of the window 3 turnably around a vertical shaft between a projected attitude and a housed attitude, and the bottom bar 13 is locked to the first or second receiving member 20 or 21 to support so that the bottom bar 13 does not move upward. The space (a) between the screen 10 and the window 3 can be enlarged by using the first receiving member 20 and reduced by using the second receiving member 21, and its structure is simplified.
