る。On the outer periphery of the connecting pipe 2, a part of the connecting pipe 2 is bulged outward to form a rib 5 projecting in the diametrical direction of the connecting pipe 2, and the rib 5 is surrounded. An annular tightening fitting 6 was attached. The fastening metal fitting 6 has a U-shaped cross section including an outer peripheral portion 6a and both side portions 6b and 6b. A notch 6c is provided on one side portion 6b of the fastening metal fitting 6, and the fastening metal fitting 6 has an annular shape. Partly cut off, and the flanges 6d, 6d are attached to both sides of the cut off end.
Was tightened with a screw 7 to form an annular shape. still,
The fastening metal 6 has a U-shaped cross section, but it is not limited to the U-shaped, and needless to say, it may have an inverted U-shaped, C-shaped or other shape. Then, the duct 3 is connected to the air conditioner 1 by screwing the ends of the spiral ribs 4 of the duct 3 into the fastening fitting 6 through the notch 6c.

部が締付金具６から外れるのを防ぐことができる。In the drawing, 8 shows an annular packing provided between the rib 5 and the edge 3a of the duct 3, but the packing 8 may be omitted. In this case, by applying the same tape 10 as that conventionally used to the outer circumference of the connecting portion between the air conditioner 1 and the duct 3, the connecting portion can be sealed. It should be noted that a notch 6e similar to the notch 6c is provided at a position where the notch 6c of the tightening metal 6 is in a diametrical line shape, and a wedge 9 is inserted from the notch 6e into the tightening metal 6 in the arrow direction. If you type in, the connection will be more stable.
The screwing of the ends of the spiral ribs 4 of the duct 3 into the fastening fitting 6 may be performed by rotating the duct 3, or by rotating the fastening fitting 6. Is also good. When the screw 3 at the end of the spiral rib 4 is screwed into the tightening metal fitting 6 by rotating the duct 3 or rotating the tightening metal fitting 6, By slightly twisting so as to cause deformation, the contact pressure between the spiral ribs 4 and 5 is increased, and the end of the spiral rib 4 is disengaged from the tightening fitting 6 by the contact pressure. Can be prevented. Further, in the case where the packing 8 is provided, the elastic deformation of the packing 8 is further applied to prevent the ends of the spiral ribs 4 from coming off from the tightening fitting 6.
