Abstract

A window-lifter drive unit for a cable-window lifter which includes a housing in which a worm gear as well as a cable drum taken along by the worm gear are provided between two mutually opposite wall parts. A bearing bolt 40 is supported with one end thereof in one of the two wall parts and at the other end thereof in the other wall part by way of a bearing bushing. The cable drum is retained at the outer circumference of the bearing bushing; a circumferential collar of the bearing bushing forms a securing member against pulling off the cable drum from the bearing bushing. Combined with a simple construction and low manufacturing costs, a partial unit including the worm gear as well as the bearing bolt can be separated without difficulty from a partial unit including the cable drum as well as the bearing bushing which facilitates assembly and repair work.
