<p>PURPOSE:To provide a hose which is constituted to suppress the occurrence of relative displacement of an inner hose part in an axial direction and to further improve assembly properties. CONSTITUTION:A hose part 1 is made of NBR/PVC and comprises a first bellows cylinder part 10; a first straight cylinder part 11; and a folded seal part 15. An inner hose part 2 formed of polyamide comprises a second bellows cylinder part 20; and a second straight cylinder part 21. The seal part 15 is folded inwardly through a thin section part 11h, and the straight cylinder part 21 is nipped between the straight cylinder part 11 and the seal part 15 to effect sealing. A mating pipe 7 is then inserted and a clamp member 4 is fastened against an outer hose part 1. In a state that the inner hose part 2 is inserted in the outer hose part 1, the protrusion part 21r of the inner hose part 2 is nipped between the regulating regulation part 17 of the outer hose part 1 and the nipping protrusion 15r of the seal part 15.</p> |
