In a drive apparatus for a pivotable window pane held pivotally at one end thereof by a window frame through hinges, an output shaft driven by an electric motor through a reduction mechanism is coupled to a first link which in turn is coupled to the other end of the window pane through a second link and a hinge. The first link and the second link are so arranged that the joint therebetween moves along an arcuate path. The output shaft is positioned at a side closer to the hinge than the center of the arcuate path is. Further, the joint moves within the outer confine of the motor and the reduction mechanism.
