<p>PROBLEM TO BE SOLVED: To reduce occurrence of kink by providing a hose comprising an inner surface layer tube formed by at least one or more layers of synthetic resin or rubber elastic material, a spiral spring surrounding the outer periphery of the tube, and a reinforcing layer further surrounding the outside thereof. SOLUTION: Thermoplastic elastomer is extrusion molded as an inner surface layer tube 1, a spiral metallic spring 2 is arranged on the outer periphery thereof, and further a braided layer 3 of a stainless soft wire is provided on the outside thereof. As the spring 2, mainly a metallic one is preferably used, and desirably the line diameter ranges from 0.3 mm to 1.2 mm. Thus, the spiral, preferably metallic spring is arranged on the outside of the inner surface layer tube, whereby the circumferential rigidity of a hose is remarkably increased. Accordingly, the flexibility of the hose will not be damaged, and even if the hose is bent, deformation of the hose can be prevented and the occurrence of kink can be prevented.</p> |
