PROBLEM TO BE SOLVED: To reduce radiation of an abnormal sound caused by the realization of high pressure of fuel control pressure, and to prevent fuel leakage by absorbing core dislocation of branch pipes and an injector. SOLUTION: In a fuel distribution pipe 1 having a pipe body 2 and two or more of branch pipes 3 for inserting/connecting an injector 10, a bellows structure part 9 for showing pipe axis directional and pipe diameter directional elasticity is arranged between a base end part 7 close to the pipe body 2 of the branch pipes 3 and a tip part 8 for inserting/connecting the injector 10. The bellows structure part 9 is covered with a cylindrical wire net body 16 to restrain pipe axis directional expansive deformation of the bellows structure part 9 by fuel control pressure, and is fixed to the branch pipes 3 on both sides of the cylindrical wire net body 16. A filter noise eliminator 20 is arranged inside the branch pipes 3. |
