Conventionally, in the joint structure of resin ducts for vehicles, as shown in FIGS.
The inner side 12a of the joint portion 12 of the rectangular cylindrical second duct 11 is closely aligned with the end portion 11 of the second duct 11.
It is formed in a.
また、結合部外側１５ａの先端縁１６は、一平

In addition, in the same alignment state, the corner 16b of the tip edge 16 and the tip edge 13
The relative distance l 1 with respect to the corner portion 13b is approximately equal to the relative distance l 2 between the side portion 16a of the tip edge 16 and the side portion 13a of the tip edge 13.

つている。 Therefore, the connecting portion outer side 15 of the first duct 14
It is difficult to bring the first duct 14 and the second duct 11 into close contact with each other and the inner side 12a of the joint part 12a of the second duct 11 to smoothly connect the first duct 14 and the second duct 11.
