An adjusting drive comprises an electric motor having a motor armature provided with a motor armature shaft, a worm transmission associated with the drive motor and having a worm shaft which is formed as a floatingly arranged extension of the motor armature shaft, the worm shaft having a free end provided with a convex end surface, a stationary running element on which the motor armature shaft is fixed in an axial direction when it is rotated in a rotary direction, so that a pitch angle of the worm shaft in connection with a flank angle of teeth of the worm shaft produce a load component extending transversely to a longitudinal axis of the worm shaft, the running element which cooperates with the convex end surface of the worm shaft having a running surface which is formed spatially relative to the longitudinal axis of the worm wheel so that it is inclined in direction of the loading component of the worm shaft.
