<p>PROBLEM TO BE SOLVED: To improve seal durability and prevent reduction of press-in workability by interposing a joining layer formed of a moisture-curing adhesive between interfaces of a hose and a rigidity pipe in hose connecting part. SOLUTION: A polar material made rigid pipe 14 is pressed-in and connected to a hose 12 made of elastomer material. A connecting layer 16 formed of a moisture-curing adhesive is interposed between interfaces of the rigid pipe 14 and the hose 12 in a hose connecting part H. In the moisture-curing adhesive, at first, adhesive strength is hardly generated. When the rigid pipe 14 is pressed in, a pseudo-slip coating is formed on an inner surface of the hose 12 and/or an outer surface of the rigid pipe 14 in the hose connecting part H by the adhesive, and a frictional resistance is sharply reduced between them. It is thus possible to improve sealing durability, and it is also possible to prevent reduction of press-in workability.</p> |
