The first control cable is guided out of a first housing part of the cable drum housing along a first direction, and the second control cable is guided out of a separate, second housing part of the cable drum housing along a second direction. Different mounting positions of the first housing part are provided in which the first housing part is in different rotational positions relative to the second housing part, with the result that the first guidance direction has a different orientation than the second guidance direction in the different mounting positions.
