ABSTRACT:
A hose 10 of the invention includes an outer hose member 12 composed of a rubber and an inner hose member 14 composed of a resin. A pair of projection ring elements 26 formed on opposite ends of the inner hose member 14 are received in a pair of inner circumferential grooves 24 formed in thick-walled tube elements 18 of the outer hose member 12. The projection ring elements extend the inner circumferential grooves 24 with such dilatation and deformation of the concavity of the inner circumferential grooves 24 enabling the thick-walled tube elements 18 to generate forces acting along the concavity of the inner circumferential grooves 24. Such forces are applied as pressing forces against the projection ring elements 26. The thick wall of the thick-walled tube elements 18 enables the pressing forces to be maintained while the projection ring elements 26 are retained in the inner circumferential grooves 24.
