PROBLEM TO BE SOLVED: To provide a front defroster nozzle that is narrow in air outlet width of an air outlet and that is able to supply air-conditioned air over the widest possible range of a windshield.SOLUTION: A retainer 3 of a front defroster nozzle device 1 is two-forked having a first branch part 10 and a second branch part 20. The air outlet width of an air outlet 60 including the first air outlet opening 61 of the first branch part 10 and the second air outlet opening 62 of the second branch 20 are set to 400 mm or less. The air outlet width of the air outlet 60 is made greater than the opening width of an introduction opening 50. The opening width of the first air outlet opening 61 is made greater than the opening width of a first introduction end part 51. In addition, the opening width of the second air outlet opening 62 is made greater than the opening width of a second introduction end part 52. Furthermore, a cross-sectional area of the channel of a choke part 35 is set to 80% or less but 60% or more of a cross-sectional area of the channel of an upstream opening.SELECTED DRAWING: Figure 4
