Abstract
A drive device includes a housing having a first housing part and a second housing part. The first housing part is axially movable in relation to the second housing part along a longitudinal axis of the housing. The drive device includes a preloading means located in the housing for axially preloading the first housing part with respect to the second housing part; a spindle rod coupled to one of the first housing part and the second housing part; and a spindle nut. The spindle nut is in threaded engagement with the spindle rod and is coupled to the other one of the first housing part and the second housing part. A stop part is at least indirectly connected to the first housing part, and a first end of the preloading means rests against the stop part.
