Description of the Related Art For example, a duct is used for air-conditioning the interior of an automobile to guide airflow from an air conditioner including a heater and a cooler to a target position in the interior of the automobile. This type of duct takes a relatively complicated shape in order to pass through the relationship between the vehicle body structure and the equipment. Blow molding means is suitable for such molding.

体等へ取り付ける方法がとられてきた。In some cases, a plurality of duct bodies need to be arranged relatively close to the duct. For example, the relationship between a so-called air-conditioning duct installed around the driver's seat of an automobile for adjusting the indoor temperature and a defrost duct for preventing fogging of window glass corresponds to this. In such a case, a method has conventionally been adopted in which a plurality of duct bodies are separately formed and separately mounted on a vehicle body or the like.

等の問題を生ずる。In this regard, it is conceived to integrally mold a plurality of duct bodies. However, in this case, since the plurality of duct bodies approach each other, the mold becomes complicated, and there are cases where molding is restricted and molding is impossible. Further, if the processing is concentrated on a specific portion of the parison, the thickness of the parison may become uneven or thin, resulting in a problem that the overall thickness balance becomes poor.

Normally, the instrument panel is a flexible panel-shaped material manufactured by resin molding, but the rigidity is increased by assembling the blow-molded duct 10 of the present invention. Of course, the panel rigidity is improved by the conventional duct, but the blow-molded duct 10 of the present invention has a higher integration since it has the integrated portion 12 having the joint portion 12. Since the blow-molded duct 10 assembled in this manner has few connecting parts, the possibility of air leakage is very small.
