a housing that is connectable to the steering column;
a gear wheel that is configured to be rotatably driven by a motor about a spindle axis, the gear wheel being mounted in a bearing assembly in the housing;
a threaded spindle that engages in a spindle nut and is axially supported by or in the housing in a direction of the spindle axis;
a retaining element disposed between a thrust bearing element of the bearing assembly and the housing, wherein the thrust bearing element includes a forming die that interacts with the retaining element and includes a forming portion; and
an energy-absorbing installation disposed between the threaded spindle and the housing, wherein the energy-absorbing installation is configured to absorb kinetic energy when the threaded spindle is repositioned relative to the housing in the direction of the spindle axis.
