しまう。For the purpose of improving duct formability and duct mounting workability, side vent ducts and side differential ducts are blow-molded integrally with a center vent duct, and blow-out ports of these side vent ducts are formed. When trying to connect the outlet of the side differential duct to each grill part that is vertically offset on the side of the instrument panel, the outlet of the side vent duct that provides high mounting strength with a large diameter is used for the instrument panel. Connect and fix to the vent grill part of the instrument, and adjust the outlet position of the side differential duct with a small diameter based on the outlet fixing part of the side vent duct with high mounting strength to adjust it to the side differential grill part of the instrument panel. Although it will be connected, in the case of ducts made of non-rubber resin, this is because it has high hardness and less flexibility. Outlet position adjustment can no longer stick.

Even when it is fastened and fixed to the panel 14, the bellows parts 5 and 5 are connected to the outlet 4a,
Since it is possible to easily adjust the bending movement of the position 4a in the up-down direction and the front-rear direction, these outlets 4a, 4a can be properly aligned and connected to the side differential grill, and fixedly connected, and integrally blow molded with a non-rubber resin material. By doing so, it is possible to achieve both improvement of duct formability and duct mounting workability and securing of mounting performance of the side differential ducts 4, 4.

In each of these, since the burr 12 generated between the molding die mating surfaces during the blow molding of the duct unit 1 is effectively used and provided at a required portion, the side differential ducts 4 and 4 end portions can be easily designed and molded. Since the material is not wasted, the structure for fixing the side differential ducts 4 and 4 to the side vent ducts 3 and 3 and the instrument panel 14 can be obtained cost effectively.
