Abstract
An adjusting drive for a steering column for a motor vehicle may include a threaded spindle that by way of an external thread engages in a spindle nut. The adjusting drive may also include a drive motor that is coupled to the threaded spindle or the spindle nut such that driving at least one of the threaded spindle or the spindle nut with the drive motor causes the threaded spindle and the spindle nut to rotate relative to one another. To reduce production complexity and improve functionality, the threaded spindle may have a core element that at least in portions is coaxially surrounded in a fixed manner by a threaded element that is configured from plastic and comprises the external thread.
