ROLL SCREEN

PURPOSE: To facilitate setting by operating an operation dial to operate a pipe receiver and a guide member, a nut member, a stopper device, and a winding pipe in conjunction with each other, thereby setting a high a high limit of winding of a screen. CONSTITUTION: An operation dial 26 is turned to disengage a control claw from a pipe receiver 32 so that the pipe receiver 32 and a guide member 34 are put into a relative rotational state. Next, the dial 26 is further turned without rotating a winding pipe 16 to move a nut member 40 to a point where it makes contact with a limiting device 42. And a screen 18 is lowered and a hand is released therefrom, and rotation of the pipe 16 is restrained by means of a stopper device 48 to stop the screen 18 at a desired point. And the dial 26 is turned in a reverse direction to bring the control claw into engagement with the pipe receiver, thereby putting the pipe receiver 32 and the guide member 34 into such conditions that the receiver 32 rotates together with the member 34. As a result, a high limit of winding can be easily set by one hand.
