Patent ID: 8329274

Claim:
A fuel hose comprising a laminated structure of a tubular resin layer and an adjoining rubber layer, the rubber layer being formed by a rubber composition containing the following (A) to (E) as essential components, the (B) being present at 0.5 to 5 parts by weight, the component (C) being present at 0.5 to 3 parts by weight, the component (D) being present at 0.01 to 0.5 parts by weight and the component (E) being present at 3 to 20 parts by weight respectively based on 100 parts by weight of the component (A), and the following (F) at less than 0.1 parts by weight based on 100 parts by weight of the following (A) as an optional component, and the resin layer being formed by a material containing a tetrafluoroethylene-hexafluoropropylene-vinylidene fluoride-perfluoroalkyl vinyl ether quaternary polymer as a main component: (A) diene rubber being at least one selected from the group consisting of a acrylonitrile-butadiene rubber, a blend of acrylonitrile-butadiene rubber and polyvinyl chloride, an ethylene-propylene-diene terpolymer and hydrin rubber; (B) a sulfur vulcanizing agent; (C) at least one selected from the group consisting of 1,8-diazabicyclo[5.4.0]undecene-7 salt, 1,5-diazabicyclo[4.3.0]nonene-5 salt, 1,8-diazabicyclo[5.4.0]undecene-7 and 1,5-diazabicyclo[4.3.0]nonene-5; (D) at least one of metallic salt of carbamate and metallic salt of thiazole, the metallic salt of carbamate being at least one selected from the group consisting of a zinc dimethyldithiocarbamate, zinc diethyldithiocarbamate and zinc dibutyldithiocarbamate, and the metallic salt of thiazole being zinc mercaptobenzothiazole; (E) magnesium oxide; and (F) zinc oxide.
