があつた。<Prior art and its problems> In combustion appliances that provide air supply and exhaust to the outdoors, it is important from a safety standpoint that the air-tightness of the air supply and exhaust pipes and the prevention of joints from coming off are important. On the other hand, from the point of view of workability, an air supply/exhaust system with good assemblability is desired in which the exhaust pipe can be easily joined. As an example of this type of air supply/exhaust system, a separate type air supply/exhaust system for a combustor, which is described in Japanese Utility Model Application Publication No. 57-4658, has been proposed. This device connects the supply/exhaust pipe body and the top of the supply/exhaust pipe by fitting between a locking piece provided on one side and a through hole provided on the other side. However, this device does not have an appropriate means for closing the gap between the engagement piece and the through hole, so there is a risk of exhaust gas leaking.

は、大きな復元力が働くようにされている。 Fitting parts 1a and 2a of the fitting inner tube 1 and the fitting outer tube 2
A hole 4 for inserting a stopper pin 3 is provided in each of the holes. The outer fitting cylinder 2 is formed in such a way that a fitting part 2a with the inner fitting cylinder 1 is widened, and the other parts have the same diameter as the inner fitting cylinder. The other end side 1b of the inner fitting cylinder 1 is widened so that it can serve as an outer fitting cylinder. Similarly, the other end 2b of the outer fitting cylinder 2 can serve as an inner fitting cylinder. A spring plate 5 is integrally caulked to the stopper pin 3. This spring plate 5
is configured to have a large radius of curvature under no-load conditions, as shown by the solid line in Figure 4B, and when it is bent as shown by the dotted line in Figure 4B, a large restoring force acts. It is like that.

嵌合内筒１が拡開されて外筒２と密着する。 To join the fitting inner cylinder 1 and the fitting outer cylinder 2, first fit the spring plate 5 with the stopper pin 3 into the fitting inner cylinder 1, and then insert the stopper pin 3 into the hole 4 of the inner cylinder 1. and have them sit down. Next, fit the fitting outer cylinder 2 into the fitting inner cylinder 1 while pushing the stopper pin 3 into the inner cylinder 1, and align the hole 4 of the outer cylinder 2 with the stopper pin 3, so that the stopper pin 3 The hole 4 of the outer cylinder 2 is also made to penetrate and protrude. When the inner fitting tube 1 and the outer fitting tube 2 are fitted together, the spring plate 5 tends to expand due to the restoring force.
The fitting inner cylinder 1 is expanded and brought into close contact with the outer cylinder 2.
