た。 As shown in FIG. 1, a typical heater air duct 1 has an inside/outside air switching device 2 and a heater unit 3 connected to each end, and a bellows 1a in the middle so that these can be connected properly. Pressure force is generated in both directions. Such an air duct 1 is generally formed by blow molding using polyethylene or polypropylene resin, but when an air conditioner is installed as an option, the evaporator is connected to the inside/outside air switching device 2 and the heater. Since the air duct 1 is installed between the evaporator unit 3 and the heater unit 3, the air duct 1 is discarded, and instead, as shown in FIG. It was connected to unit 3 by another band or duct 6.

A bellows 11 is provided between the intermediate flange 11d and the round flange 11c that protrude outward from the intermediate portion.
A is provided. A line is carved around the intermediate flange 11d so that it can be divided into a first cylindrical part A on the inside/outside air switching device side and a second cylindrical part B on the heater unit side at this line. . If both parts A and B are divided by this line, the cross-sectional opening will be
The shape is such that it can be connected to the outer periphery of the outlet opening of the evaporator 4. Therefore, when installing the air conditioner, this duct 11 is connected to the intermediate flange 1.

A part of the air duct, which was previously discarded when installing an air conditioner, can be reused, improving work efficiency and reducing costs. In addition, since the second cylindrical part is formed with a bellows part, it is possible to absorb assembly errors when assembling the air duct, regardless of whether the air conditioner is installed or not. Installation work can be done easily. moreover,
Since the cutting line is engraved on the intermediate flange, it is possible to accurately cut the first cylindrical part and the second cylindrical part when cutting the first cylindrical part.
