Abstract: The invention relates to a spindle drive for converting between a rotational motion and a translational motion comprising a spindle for translational motion and a spindle nut for rotational motion, wherein the spindle and the spindle nut are coupled to each other by means of threads. The spindle nut comprises a reservoir in axial extension of the thread of the spindle nut, in which reservoir a segment of the spindle extends. A lubricant is accommodated in the reservoir, and a displacement element is attached to the spindle in the region of the reservoir, which displacement element extends further outward radially than the thread of the spindle.
