PROBLEM TO BE SOLVED: To reduce the flow passage resistance of a guide flow passage for a side duct, and to enhance the layout versatility of the branching position of a center duct. SOLUTION: An introduction chamber part 20, a center duct, and right and left side ducts 24 and 26 are integrally blow-molded with each other. In a vehicle air-conditioning duct structure, demarcating members to demarcate an introduction chamber 20 of the introduction chamber part into a guide flow passage 98 for the center duct and guide flow passages 100 and 102 for the right and left side ducts are provided. The introduction chamber part 20 has right and left introduction chamber walls 36 and 38 facing each other in the width direction of a cabin, and the right and left introduction chamber walls 36 and 38 are provided so that the distance in the width direction of the cabin is increased from the upstream side to the downstream side of the introduction chamber 20. The demarcating members 72 have a pair of right and left partition walls 74 and 76 facing each other in the width direction of the cabin 2, and the pair of right and left partition walls are formed so that the distance along the width direction of the cabin 2 is larger on the downstream side than on the upstream side of the introduction chamber.
