Claim:
Actuating device comprising: a drive unit comprising an electric motor, which motor is arranged in a housing and directly drives a drive shaft; a gear unit comprising a drive gear driven by the drive shaft and arranged on the drive shaft at least in a rotationally fixed manner, one or more planetary gears, each planetary gear comprising a double gear having a larger gear wheel and a smaller gear wheel, supported on an axle in a fixed position and so that the planetary gear can pivot, and an internally toothed gear or internally toothed gear segment that is arranged on an output shaft in an at least rotationally fixed manner, wherein the drive gear in a first gear stage meshes with at least one planetary gear, whereby the drive gear drives the larger gear wheel of the double gear, and the smaller gear wheel, which faces a direction of an output side, in a second gear stage meshes with the internally toothed gear or internally toothed gear segment, so that the output shaft can be driven via the two gear stages; and a cover fixed to the housing of the drive unit and the outside of the gear unit, arranged so that a bearing of the output shaft is arranged in the cover.
