A defroster nozzle is provided inside an instrument panel below a front glass plate, and its length in the direction of vehicle width is gradually increased from a suck-in opening to a blow-out opening. The suck-in opening is connected to an air conditioning unit, and has a bent portion at the middle thereof. The inside of the defroster nozzle is divided by partition walls into a central chamber and side chambers. The length of the central chamber as viewed in the direction of vehicle width is gradually increased from the suck-in opening to the blow-out opening, and the opening areas of the suck-in opening and the blow-out opening of the central chamber are equal to each other. The central portion of the side wall of each of the side chambers has a bent portion. The length of each of the side chambers as viewed in the direction of vehicle width is increased gradually from the bent portion to the blow-out opening, and at each of the bent portion the cross-sectional area of the side chamber is smaller than the opening area on the side of the suck-in opening. At each of the side chambers, the opening area on the side of the blow-out opening is smaller than the opening area on the side of the suck-in opening.
