ABSTRACT:
In a roller shade for an opening such as a rear windshield of an automobile, when the shade is full closed, the pull rod is intentionally bent so as to fully conform to the peripheral edge of the opening. The bending of the pull rod can be achieved either by an axial force which may be produced by gradually reducing the distance between a pair of guide members extending on either lateral side of the opening as the pull rod moves up or by a lateral force which may be produced by placing a slope on which the pull rod rides over as it reaches its final position for fully covering the opening. By controlling the bent shape of the pull rod in a suitable manner, it is possible to entirely cover the opening without leaving any uncovered gap.
