Abstract: In an operating device for operating body components of a vehicle, it is provided, with a view to obtaining simple automatic operation as well as unrestricted manual operation, that an electromechanical drive unit comprises at least one drivable first stop element and a power transmission unit at least one second stop element which is connected to the body component, the stop elements being able to bear against each other for transmission of an operation power in a direction of power transmission and to be spaced from each other for uncoupling the drive unit from the power transmission unit in the direction of power transmission. There is no need for any electromechanical coupling for uncoupling purposes.
