る。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is in the field of utilizing plastic hollow bodies, and is particularly suitable for ducts, pipes, tubes, tanks, etc. which require assemblability and airtightness when assembled with a counterpart. It is effective and can be used for automobile ducts, pipes, tubes, resonators, etc., and home appliance pipes, etc.

Insert a soft hose or duct such as a rubber hose, or slit the duct as shown in FIG. 11 and insert a rubber insulator or the like to improve the assemblability and tighten it with an assembling hose band. It was airtight.

部品５４との間に介在させなければならないため、狭い
空間や短い距離で採用することは困難であった。また、
部品もホースとその締付バンドが必要なため部品点数が
増し、組付の工数も多くなる欠点がある。In the above-mentioned conventional configuration, in the example in which the rubber hose or the like shown in FIG. 10 is interposed, the assembly is performed unless the soft hose 52 or the like is interposed between the mating component 54. Since it is not possible, a method of covering the assembling portion 51 of the hard plastic hollow body with the soft hose 52 and then tightening the hose band 53 to keep the airtightness has been adopted. In this example, since a soft hose or the like has to be interposed between the hose and the counterpart component 54, it is difficult to employ it in a narrow space or a short distance. Also,
As for parts, there is a drawback that the number of parts is increased and the number of assembling steps is increased because a hose and its tightening band are required.

The processing of 66 is required, and further, the processing of the slit 67 to cope with the change of the diameter at the time of assembling and tightening is required. An insulator 68 made of a soft material is attached to the hollow body assembly portion thus processed.
After assembling, attach it to the mating part 69 and attach the hose band 7
With 0, the tightness is maintained. In this case, cutting and slitting are required at the assembling part of the hard plastic hollow body, and a soft insulator is also incorporated, which requires a lot of machining and assembling man-hours.
