ABSTRACT:
A rolling screen comprises a screen case, a take-up shaft arranged rotatably about a central axis thereof within the screen case, and a screen wound on said take-up shaft so that the screen can be wound out of said screen case. The take-up shaft is normally biased in a screen-winding direction by a torsion spring. An outer peripheral surface of the screen wound on the take-up shaft is always maintained in contact with an inner wall of the screen case, said inner wall being located in a direction of winding-out of the screen, by pulling force applied to the screen upon extension of the screen or resilient force of a pressing spring when the screen is wound out or wound in.
