Abstract

A drive device (1) for motorized actuation of a functional element of a motor vehicle has an electric motor (2) with a motor shaft (3) and also has a worm shaft (4) of a worm gearing. A first end of the worm shaft is connected to the motor shaft (3) and a second end is received in a radial bearing (5). The radial bearing (5) has a bearing body (21) with an outer surface mounted in a housing (11) and at least one annular bearing element (24) is mounted to the worm shaft (4). The bearing element (24) is elastic at least in a partial region to ensure compensation for tolerances in the region of the radial bearing.
