Abstract
An adjustment drive for a steering column adjustable by motor includes a threaded spindle with an axis. The threaded spindle engages in a spindle nut, a drive unit and a gear wheel connected to the spindle nut or the threaded spindle for rotation therewith, which is driveable to rotate about the axis by the drive unit and rotatably mounted about the axis in a bearing housing in an arrangement between two outer bearing rings axially supported at the bearing housing. The outer bearing rings each have, on their facing sides, a circumferential outer bearing face coaxial to the axis, the outer bearing face in each case lying opposite a bearing face on the end side at the gear wheel. At least one outer bearing ring is axially resiliently supported at the bearing housing by an elastic preloading element that axially braces the two outer bearing rings together.
