<P>PROBLEM TO BE SOLVED: To provide a resin tube for a fuel line which has a necessary sufficient heat resistance in a high-temperature environment such as in an engine room although it is made of a thermoplastic resin. <P>SOLUTION: A first heat-resistant protection resin layer 12 made of foaming TPE resin is formed on an outer peripheral surface of a main body tube 10 of thermoplastic resin. A second heat-resistant protection resin layer 14 made of flame-resistant TPE resin is so formed as to overlap the first heat-resistant protection resin layer 12. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
