Proposed is a functional device which is arranged on the outer side of a vehicle body, comprising a base element (18) and at least one pivoting element (20A) which is pivotable with respect to the base element (18) between two end positions. According to the invention, a multi-linkage mechanism is articulatedly connected to the base element (18), which multi-linkage mechanism comprises at least two linkages (24, 26) which are articulatedly connected with their ends remote from the base element (18) to the pivoting element (20A) which is pivotable with respect to the base element (18), with one of the linkages (24, 26) being connected to a drive device and with a spring device acting on at least one of the linkages (24, 26), which spring device is preloaded into the end positions of the pivoting element (20A) and counteracts the mass force of the latter.
