An air conduction device suitable for a sports car motor vehicle extends in a lateral direction of the vehicle, adjacent to a tail lid. The air conduction device can be moved by an activation device out of a resting position into an operating position and vice versa. In order to optimize the air conduction device in functional and structural terms, it is hinged on the tail lid by a swing arm device which is separably connected with the activation device by means of which the air conduction device is moved out of the resting position into the operating position.
