<p>The present invention particularly provides a lifting plate of a window regulator with retainers that are operably interconnected by means of a motion-transmitting element for a tilt-free operation of a window screen. The window regulator comprising a slidable lifting plate mounted on a vertical guide rail, a pair of flanges disposed on the rear side of lifting plate to mate with said guide rail and to provide a tilt-free sliding support to the lifting plate. A pair of retainers with locking means is operably connected by means of a motion-transmitting element. The motion transmitting element is disposed to form a contact-free crossover of said motion-transmitting element on the rear side of the lifting plate.</p>
