Window regulating device for a window glass of a vehicle door or the like

摘要

A stationary guide rail has "V" shaped sides which partially enclose a slotted tube and which have a section which endows on the rail a high "second moment of inertia". A slide member has a pair of arms which embrace the external surfaces of the "V" shaped sides and an extension which passes through the slot in the tube in which an axially movable cable is disposed. The extension has a loop at the end thereof which tightly grips the cable. A handle is connected to a gear wheel meshing with a helical ridge formed on the cable so that winding of the handle very smoothly raises and lowers the window glass.
