Abstract

An actuator for a motor vehicle, more specifically for a motor vehicle seat. The actuator comprises an electric motor having an output shaft, a gear that is connected to the output shaft and including a gear housing having two partially cylindrical exterior surfaces, and a spindle that communicates with the gear, the spindle defining a threading and runs transversely with respect to the output shaft. Further, the actuator comprises a gear retainer that (a) forms a surrounding grip around the gear housing, in which (b) the gear housing is held pivotal about a pivot axis that runs parallel to the output shaft, that (c) has two partially cylindrical interior surfaces, each mating the exterior surfaces against which they fit, and that (d) includes a recess or two recesses for the passage of the spindle. The gear retainer has fastening holes running parallel to the pivot axis.
