Abstract: The invention relates to a gearing mechanism for the adjustment of two reciprocally adjustable parts (60, 61), especially vehicle parts of a seat adjustment device, a window lifter or a sunroof, wherein the first of the parts (60) has a nonrotating spindle (62) or a fixed tooth rack. The gearing mechanism is formed with a wormwheel (4, 41), which has a spindle nut (42) non-rotatingly connected thereto in order to drive the spindle (62) or a worm non-rotatingly connected thereto in order to drive the tooth rack, with a worm (3, 31) that can be driven so as to transfer a driving force to the wormwheel (4, 41), and with a gear housing (1), which houses the worm (3) and wormwheel (4) in a supporting manner, and which can be connected immovably with the second of the parts (61) in its adjusting direction, wherein the gear housing (1) is formed of a single-piece body with a worm support (14) and a wormwheel support (19).
