PROBLEM TO BE SOLVED: To provide an air guide duct capable of preventing dewing, capable of preventing generation of an abnormal sound of contact with the other member and capable of absorbing noise of an air conditioner unit. SOLUTION: This air guide duct 10 is composed of a first base body 12 and a second base body 14 joined in the lengthwise direction. The first base body 12 is molded from a resin sheet material having rigidity required for holding a reguired shape, and has in a prescribed position an air inflow port 18 matching to an air conditioner unit and an air outflow port 16 matching to the air supply part of an instrument panel. The second base body 14 is molded from a foaming resin sheet material, and defines an air flowing space 28 inside by being joined in the lengthwise direction to the first base body 12. Since the second base body 14 is excellent in heat insulating performance and sound absorptivity, the occurrence of dewing is prevented by setting the outside surface area of the second base body 14 wide, and generation of an abnormal sound by contact with the other member can also be prevented. |
