An adjusting drive for a steering column for a motor vehicle may include a threaded spindle with an external thread that engages in a spindle nut and a drive unit that is coupled to the threaded spindle or the spindle nut such that the threaded spindle and the spindle nut are able to be rotatably driven relative to one another by overcoming a screw resistance. To permit an optimized adjustment over the entire adjusting region, the threaded spindle includes at least one actuator portion and at least one transition portion. The transition portion is configured such that the screw resistance of the spindle nut is lower in the transition portion than in the actuator portion.
