した、 ことを特徴とする巻取式スクリーン装置。[Scope of Claim for Utility Model Registration] A screen equipped with a heavy bar that provides an appropriate tensile force at the tip is wound around a winding shaft that is rotatably supported in a screen box that is attached to the top of an opening in a building. In a winding type screen device in which the screen can be manually opened and closed by rotating the winding shaft by operating an operator, the rotating shaft connected to the winding shaft of the screen is
The one-way clutch is installed in the case of a one-way clutch having the above-mentioned operator attached to the end of the screen box, and when the screen is raised or lowered by operating the operator, the operating force is applied to the rotation of the winding shaft. A winding type screen device characterized in that, although the force is transmitted as a force, the winding shaft is capable of applying a resistance force in the direction of restraining the movement of the screen against the force in the pulling direction acting on the screen. .
