Abstract
The invention involves a gearbox, especially for adjustment devices in motor vehicles, with a plastic worm drive. The invention provides that the worm drive has an encircling, circular flat contact surface perpendicular to the worm axle and a number of removal pockets in the form of recesses that are interposed axially between contact surface and the worm axle and at the same time arranged in a level recessed to the level of contact surface, whereby an encircling bevel is formed in the transition area from level of removal pockets to the level of the circular contact surface.
