<P>PROBLEM TO BE SOLVED: To provide marine hose capable of detecting liquid fuel gradually leaking. <P>SOLUTION: A conductive elastomer member 30 is provided in a hose main body 10. The conductive elastomer member 30 is swelled by crude oil, and a resistance value is increased by swelling. The resistance value of the conductive elastomer member 30 is detected by a detector 41. Therefore, if the crude oil gradually leaks from an inside rubber layer 11, the resistance value of the conductive elastomer member 30 is increased by swelling, and its resistance value is detected by the detector 41. Namely, according to the resistance value detected by the detector 41, the crude oil gradually leaking from the inside rubber layer 11 can be detected, so that it is extremely advantageous for preventing environmental pollution due to the leakage of the liquid fuel from the hose main body 10. <P>COPYRIGHT: (C)2009,JPO&INPIT |
