Ventilating duct for a ventilation device of a motor vehicle

A ventilating duct for a ventilation device of a motor vehicle, comprising:

• a housing including a first housing portion and a second housing portion, the housing providing a main duct that extends, in a longitudinal direction, through the first housing portion and the second housing portion and that defines a flow cross-section, the first housing portion being configured to receive an air flow from an air conditioning system, and the second housing portion being configured to face a passenger cell of the motor vehicle and provide the air flow to the passenger cell;
• a disk configured to rotate about an axis of rotation that extends in the longitudinal direction and to direct an air flow from the first housing portion to the second housing portion;
• and a partition disposed in the second housing portion and arranged downstream of the disk, the partition dividing the main duct into at least two sub-ducts in the second housing portion, wherein the first housing portion and the second housing portion each includes a flange, and wherein the partition in its direction of extent along a longitudinal axis of the ventilating duct is formed transversely relative to the disk, wherein the flange of the first housing portion is connected to the flange of the second housing portion so as to form a widened region of the housing, wherein the disk is accommodated in the widened region of the housing.
