1 is a duct and a flange 2 joined to a mating duct 6 at a mouth end.
A longitudinal rib 3 for preventing cracks is formed in a parting line portion by a mold 7 as shown in FIG. 4, and a reinforcing rib 4 which is in contact with the back side of the flange 2 is integrally formed on an extension of the rib. is there.

できる。According to the present invention, in a blow-molded synthetic resin air-conditioning duct joined to a mating duct flange via a seal material, the duct extends outward along a duct parting line. Since the longitudinal rib for preventing cracking is formed and the reinforcing rib abutting on the back side of the flange is integrally formed on the extension thereof, the rigidity of the flange is increased by the reinforcing rib and air leakage can be prevented. In addition, the duct can be prevented from cracking by the longitudinal rib for preventing cracking along the parting line.
