PROBLEM TO BE SOLVED: To provide an air conditioning duct for vehicles which equalizes the air flow at the corners of the duct and prevents the air flow from generating sound when it passes the corners without cutting and opening a blow-molded duct. SOLUTION: The air conditioning duct is provided with a duct body 1, the whole of which is formed into a cylindrical shape by blow molding and a wind guiding plate 2 which is incorporated in a projected section 12 from the cylindrical opening of the duct body 1 for parting an air flow passage R together with the projected section 12. In such air conditioning duct, the distribution of the flow velocity of the air at a corner section C is equalized by projecting a projected section 12 toward the inside of the air flow passage R with the peripheral wall 11 of the duct recessed at the corner section C of the air flow passage R and by means of the wind guiding means 2.
