    • PROBLEM TO BE SOLVED: To provide a fuel delivery pipe which ensures the sufficient strength of an inlet pipe even if it is formed integrally with the fuel delivery pipe.SOLUTION: The resin fuel delivery pipe 10 includes a pipe body 11 in which a fuel passage 11a is formed, the inlet pipe 13 which leads a fuel into the pipe body 11, and a plurality of injector fitting portions 14 which distribute the fuel lead into the pipe body 11 from the fuel passage 11a to a plurality of injectors. The inlet pipe 13 has an inner diameter smaller than the inner diameter of the pipe body 11, and is formed integrally with one end of the pipe body 11 via a connection 12 having a slope 20 with a diameter gradually reducing toward the base of the inlet pipe 13.
    • 要解决的问题:提供一种燃料输送管,其确保入口管的足够的强度,即使其与燃料输送管一体形成。 解决方案:树脂燃料输送管10包括其中形成有燃料通道11a的管体11,将燃料引入管体11的入口管13和多个喷射器配合部分14, 燃料从燃料通道11a进入管体11到多个喷射器。 入口管13的内径小于管体11的内径,并且经由具有直径逐渐减小的斜面20的连接件12与管体11的一端一体地形成为朝向入口的底部 管13.版权所有(C)2012,JPO&INPIT
