Abstract
A power window apparatus for opening and closing a curved window glass having a comparatively large curvature in the direction of its curvature is provided with a fixedly mounted reversible motor, a curved screw having curvature nearly equal to the curvature of the curved window glass and fixed in parallel to the curved window glass, and a movable unit fitted onto said curved screw and connected to the motor and said curved window glass. A flexible drive shaft transmits the rotation of the motor to a worm gear in mesh with a worm wheel disposed in threaded connection on the curved screw to move the movable unit along the length of the screw.
