The present invention provides an actuating device for a wind deflector device in a vehicle, with a roof opening and a roof closure element, wherein the actuating device has at least one actuating cable which can be coupled to a sun-shielding device, wherein the actuating cable can actuate the sun-shielding device when it is coupled to the sun-shielding device, wherein the actuating cable can be moved in a first direction in which the sun-shielding device uncovers the roof opening, wherein the actuating cable can be decoupled from the sun-shielding device in a predetermined position, and wherein, in the state in which it is decoupled from the sun-shielding device, the actuating cable can be moved further in the first direction and, in the process, can adjust the wind deflector device.
