Abstract
There is provided a window screen configured in such a manner that first and second screens are wound around a winding shaft together with a number of dimming slats attached therebetween in which bottom bars of lower ends of both screens come into stable contact with a lower frame of a screen frame. The first and second screens and the slats attached therebetween at regular intervals so as to be freely tiltable are wound around the winding shaft, both side ends of the first screen engage guide rails so as to be freely slidable, and bottom bars guided individually by side frames are attached to lower ends of both screens. Both screens are set so that either one of the bottom bars at the lower ends thereof comes into contact with the lower frame of the screen frame in an arbitrary inclined orientation that the above-described slats may have in a state in which both screens are extended in the screen frame in a tensed manner.
