<p>PROBLEM TO BE SOLVED: To restrict the occurrence of permanent set in fatigue while improving the creeping property in the case of connection using a housing type joint by inserting a cylindrical reinforcing material made of metal or resin having a rigidity higher than that of a resin tube into a connection part to a tube end so as to reinforce the connection part to the tube end. SOLUTION: A cylindrical reinforcing member 12 made of metal and provided with a cylindrical flange at a tube end thereof is inserted into a resin tube 16 to be used for housing type joint till the flange abuts on the tube end surface. The resin tube 16 is formed with a reinforcing plate 17 made of metal and to be installed in a peripheral grove 13 so as to have an L-shaped cross section, and fitted so that the reinforcing plate 17 made of metal abuts on a side, which a housing abuts on. In the case of connecting the resin tube 16 and a metal tube, this housing type joint is used for similar connection. With this structure, creeping property in case of connecting the tube and the resin tube 16 to each other with the housing type joint is improved, and the tube and the resin tube 16 can be connected for a long time without relaxation.</p> |
