PROBLEM TO BE SOLVED: To provide a screen device with a heat insulating air layer formed between double-spread screens, as a simple low-cost device. SOLUTION: The screen 6 spread doubly with the air layer 7 held between by folding is wound on a winding shaft 10 in a body case 1, and a folding shaft 12 winding the intermediate part of the screen is supported to a movable stile 4 movably guided to the facing receiving frame 2 side. A screen holder 16 selectively holdable to the body case and the movable stile is mounted to the distal end of the screen folded by the folding shaft. Fastener half bodies 28 engaged with a slit 26 provided along the guide frame 3 of the movable stile are mounted to both sides in the width direction of a non-folded portion 6a located between the winding shaft and the folding shaft of the movable stile when the screen is spread doubly.
