PROBLEM TO BE SOLVED: To enable positioning of a fuel injector and facilitate production by arranging an extended portion as a positioning member for the fuel injector on a fuel rail beam made of metal plate, and preventing relative rotation of the fuel injector in respect to an injector cup while holding the injector by means of the injector cup. SOLUTION: A fuel rail beam 9 has a closed section for fuel flowing, composed of rail members 16, 17 respectively having a U-shape formed section prepared by press molding. An injector cup 12 is projected integrally from the rail member 16. An extended portion composed of a linear portion 15a and a guide portion 15b is formed on only one side wall of the injector cup 12 so as to be extended along the injector cup 12 to the vicinity of a leading end of the cup 12. A fuel injector 1 with two jet holes is inserted into the injection cup 12 of the fuel rail beam 9 fixed to the position with specified relation to a suction pipe 8. The guide portion 15b of the extended portion 15 is inserted into a gap formed as a positioning part on a connector terminal 19 connected to the fuel injector 1 so as to prevent its rotation. |
