Cable window regulator for motor vehicle, has drum whose conical shape is provided on part of its axial length to define reduced diameter in drum area in which cable upper part attains zone, where glass pane is closer to closing position

摘要

The regulator has an electric motor rotatably driving a drum (2) with a helical guiding groove that guides a cable rolled in a part of a groove (3) of the drum. The cable is connected with a slide valve guided in a rail and fixed at a glass pane to be displaced. Diameter of the drum varies in its axial direction. The drum has a conical shape provided on a part of its axial length to define a reduced diameter in a drum area in which a cable upper part raising the slide valve attains a zone, where the glass pane is closer to its closing position in the zone.
