  • Patent number: 8795042
    Abstract: Provided is a defroster nozzle 4 which blows out air to an inner surface of a windshield 2 of a vehicle 1. The defroster nozzle 4 includes center-duct 45 forming member 41 and two end-portion-duct forming members 50. The center-duct 45 forming member 41 forms a center duct through which the air circulates, and has a center ventilation outlet 47 through which the air in the center duct is blown out to the inner surface of the windshield 2. The two end-portion-duct 54 forming members 50 are coupled respectively to two joint end portions 42, on outer sides in the vehicle width direction, of the center-duct forming member 41. Each end-portion-duct forming member 50 forms an end-portion duct which communicates with the center duct, and each end-portion-duct forming member 50 has an end-portion ventilation outlet 55 through which the air in the end-portion duct is blown out to the inner surface of the windshield 2.
