PROBLEM TO BE SOLVED: To provide a fuel rail capable of securing support rigidity of a boss part for attaching a fuel pressure sensor with a simple configuration without complicating the configuration.SOLUTION: A fuel rail includes; a pipe body 11 having a fuel passage 12 through which pressurized fuel is supplied from a fuel supply source; a first fixing bracket 20 in which an injector attachment part 22 joined to an outer peripheral surface of the pipe body 11 and a fixing boss part 24 are integrally formed; and a second fixing bracket 30 in which a boss part 35 for attaching a fuel pressure sensor, and a fixing boss part 40 are integrally formed on a bottomed cylindrical housing body 31 having a pipe holding hole 32 into which one end of the pipe body 11 can be inserted. The pipe body 11 is held by the first fixing bracket 20 and the second fixing bracket 30, and rigidity of the fuel rail 1 can be secured. The fixing boss part 40 for attachment to an engine body and the boss part 35 for attaching the fuel pressure sensor are integrally formed in the second fixing bracket 30, and support rigidity of the boss part 35 for attaching the fuel pressure sensor is improved. |
