An adjusting device for positioning a load comprises a threaded spindle, which is connected in the region of a longitudinal end to a carrier toothed wheel so as to be fixed with respect to rotation relative to it and so as to be fixed with respect to displacement axially, and a spindle nut which is arranged on the spindle thread and which is displaceable axially by means of a rotation of the threaded spindle for positioning the load. A fastening portion of the threaded spindle which is formed in the region of the longitudinal end of the threaded spindle has, in addition to a cylindrical portion which is received by a cylindrical portion of the through-opening of the carrier toothed wheel and in which torque is transmitted between the carrier toothed wheel and the fastening portion by a key, another conical portion which is situated closer to the longitudinal center of the threaded spindle and which widens in direction of the longitudinal center of the threaded spindle and which is received by a conical portion of the through-opening of the carrier toothed wheel, wherein the conical portion of the fastening portion and the conical portion of the carrier toothed wheel are clamped against one another by a clamping nut.
