The window glass for a vehicle door is mounted at its lower edge in an elongated sash. The glass is raised and lowered by a regulator attached to the sash. A pair of guides (pulleys or slides) are fixed to each end of the sash and a cable, anchored to the door at points at the top and bottom of sash movement, extends parallel to the direction of window movement from the anchors to the sash and around the guides such that any up or down movement of either end of the sash is transferred to the other end so that both ends move together, thereby preventing tilting of the glass.
