PROBLEM TO BE SOLVED: To prevent twist of an injector and excessive deformation of fuel piping by absorbing difference of expansion between a cylinder head and fuel piping from temperature difference or the like. SOLUTION: Tip parts of several injectors I corresponding to each cylinder of an engine are mounted on mounting holes 5 of the cylinder head H. Head parts of the injectors I are installed in plural injector installation holes 4 provided along a pipe wall of fuel piping 1. The fuel piping 1 is fixed on the cylinder head H at fixing bolt holes 2 provided at plural positions in a longitudinal direction on pipe wall. Two adjacent fixing bolt holes are arranged in a shape bending in a V-shape. The bend part 12 deforms and follows expansion of the cylinder head H to prevent misalignment of the injector installation holes 4 and the mounting holes 5. |
