Abstract
A window regulator apparatus for moving a window glass in the vertical direction of a vehicle door incorporates a plurality of pulleys rotatably supported on the vehicle door, a drum rotatably supported to the vehicle door, and a cable jointed to the window glass, guided to the pulleys and looped around the drum. The drum includes a first spiral groove which supports one end of the cable and a second spiral groove which supports the other end of the cable. The second spiral groove is formed to spiral in a direction opposite the first spiral groove. The extending points of the cable relative to the first spiral groove and the second spiral groove are defined to gradually change where the cable releases from the drum in the radial direction of the drum by the rotation of the drum.
