An axially adjustable steering column for motor vehicles has an exterior tube, which is stationarily held on the vehicle body, and an interior tube which is aligned coaxially with respect to the exterior tube and is received in an axially displaceable manner. With a motor transmission unit fastened to the exterior tube, the interior tube is driven to move back and forth axially via a spindle drive. In order to achieve a reduction of the required components and of the mounting expenditures, the interior tube has at least one radially projecting web-shaped wing, and the exterior tube has at least one longitudinal slot recess which is penetrated by the wing of the interior tube with little play. The spindle nut of the spindle drive is thus stationarily arranged on the web-shaped wing of the interior tube, and the spindle is stationarily provided on the exterior tube.
