[Object] To provide a window screen configured in such a manner that first and second screens 16, 17 are wound around a winding shaft 12 together with a number of dimming slats 18 attached therebetween in which bottom bars of lower ends of the both screens come into stable contact with a lower frame of a screen frame. [Solution] The first and second screens 16, 17 and the slats 18 attached therebetween at regular intervals so as to be freely tiltable are wound around the winding shaft 12, both side ends of the first screen engage guide rails 24 so as to be freely slidable, and bottom bars 26, 27 guided individually by side frames 23 are attached to lower ends of the both screens. The both screens are set so that either one of the bottom bars 26, 27 at the lower ends thereof comes into contact with the lower frame of the screen frame in an arbitrary inclined posture that the above-described slats may have in a state in which the both screens are extended in the screen frame in a tensed manner. |
