ーであり、少なくとも２本必要とする。(Prior Art) FIG. 3 shows an air-conditioning duct system arranged in a front portion of a vehicle compartment of an automobile. The warm air from the heater box 1 is blown into the vehicle compartment through a connection duct (not shown) and a center duct 2 from a center register 3 located at the center of an instrument panel (not shown). Further, cold air or normal air from the heater box 1 is passed through the first bypass duct 4 and the second bypass duct 5 to the center duct 2
Then, it is blown into the vehicle compartment from the center register 3. By the way, the connection between the opening 6 that opens in the vertical wall of the center duct 2 and the opening 7 of the second bypass duct 5 that is fitted therein is performed by moving the second bypass duct 5 forward from the front side. (Note that the claw-shaped projection shown by 8 in FIG. 2 is peculiar to the present invention and is not in the conventional example.) (Problems to be solved by the invention) An instrument panel is located behind the second bypass duct 5. However, since it is difficult to secure a sufficient rear space, in the conventional example, the second bypass duct 5 is used.
There was a problem that the work of connecting the to the center duct 2 was very difficult. FIG. 4 is a generalized illustration of such a problem. A first duct (corresponding to a second bypass duct) b in which the opening a is bent and a second duct in which the opening c is linear are shown. (Corresponding to the center duct.) When connecting d with each other in a fitted state, it is difficult to connect the ducts b and d unless a sufficient space is provided behind the first duct b. There is. In addition, e, f
Is a set screw that fastens both openings a and c in a fitted state, and requires at least two set screws.

A second duct having a projecting opening to be fitted, in a duct coupling structure that is joined in a fitted state, has a claw shape that engages a bent portion of the inner surface of the tip opening at one side edge of the projecting opening. A protrusion is formed so as to project, and one side portion of the tip opening portion is locked between the claw-like protrusion and the wall surface of the base pipe portion of the second duct at the time of connection, and the other side portion of the tip opening portion and the protrusion. It is characterized in that the opening is configured to be fastened with a fastener.
