1. A drive device for an opening mechanism to open a movable opening element of a vehicle, the drive device comprising:
a drive unit to produce a drive torque;
a housing with a mounting side that is oriented towards a vehicle part of the vehicle to mount the drive device;
a transmission to increase the drive torque of the drive unit, the transmission comprising a first gear unit on the driven side that includes a first gear that has a first rotational axis and a first radius, and includes a second gear unit on the output side for coupling to the opening mechanism and having an output axis; and
a cover element provided inside of the housing,
wherein the first gear unit and the second gear unit are in operative connection with one another,
wherein the output axis extends in an output region between the mounting side and the first rotational axis, and has a distance from the first rotational axis that is smaller than the first radius,
wherein the second gear unit has a second gear for rotation about the output axis,
wherein the first gear and the second gear are in operative connection through a third gear that is axially connected to the first gear,
wherein the first gear and the second gear are separated from one another by a cover of the cover element, and
wherein the housing has a spreading geometry via which at least two retaining elements of the cover element, which extend from the cover to a housing cover of the housing, are adapted to be pressed in opposite directions during mounting of the first and second gear units so that the cover element is immobilized between a first housing element of the housing and the housing cover.
