<p>PURPOSE:To let static electricity, generated by friction between fuel liquid such as gasoline and the inner wall of a hose, always escape from both end parts of the hose so as to prevent the generation of sparks by using synthetic resin with conductivity imparted thereto for the innermost layer of the hose. CONSTITUTION:An automobile fuel piping hose is provided with an innermost layer 1 made of synthetic resin and that with conductivity imparted to this innermost layer 1. The automobile fuel piping hose is formed of three layers, that is, the innermost layer 1 formed of fluororesin with conductivity imparted thereto, an intermediate layer 2 formed of synthetic resin other than fluororesin and disposed at the outer periphery of the innermost layer 1, and an outer layer 3 formed of rubber elastic material and disposed at the outer periphery of the intermediate layer 2. The fluororesin with conductivity imparted thereto can be obtained by dispersing a conductive agent and set in such a way that the volume resistivity is approximately 10<10>OMEGA.cm or less.</p> |
