Zusammenfassung:PROBLEM TO BE SOLVED: To prevent sealing performance between a fuel injection valve and a delivery pipe from being deteriorated. SOLUTION: A delivery pipe 17 has a plurality of connecting parts 19 to which fuel injection valves 16 for directly injecting fuel to a combustion chamber are connected, and it is mounted on a cylinder head 14 by a bolt 25. The axis L2 of the bolt 25 intersects a flat surface F including the axis L1 of respective fuel injection valves 16 on the cylinder head 14 side from the delivery pipe 17. Therefore, force f2 acting on the delivery pipe 17 and force f1 resisting fuel pressure to be applied to fuel injection valve 16 act on points P2 and P1 by clamping force of the bolt 25. Accordingly, rotational displacement of the delivery pipe 17, based on force f1, f2 is restrained.
