<p><P>PROBLEM TO BE SOLVED: To provide a flexible pressure resistance-wearproof hose which reduces weight and improve wear resistance and durability. <P>SOLUTION: The hose is equipped with a soft body part 2 roughly flat in inner surface and a spiral hard core material part 3 provided in an outer surface or the inside of the soft body part 2 for reinforcing this soft body part 2, wherein the hard core material part 3 consists of a hard synthesis resin or a metal wire, and the soft body part 2 consists of a durable thermoplastic elastomer. When the hard core material part 3 consists of the metal wire, the metal wire is desirable to be a coated wire in which the periphery of the metal wire is coated by the thermoplastic elastomer layer. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
