Deformation of a delivery pipe in which injectors for injecting fuel into the combustion chambers of corresponding cylinders in an internal combustion engine are accommodated, is suppressed, thereby preventing deterioration of the fuel sealing. At least two mounting portions are provided on respective lengths of the delivery pipes that extend outward from opposite ends of a length of the delivery pipe along which injector-inserting portions are disposed for accommodating the injections. This arrangement of the mounting portions prevents deformation of at least the length of the delivery pipe in which the injector-inserting portions are disposed, thereby preventing deterioration of the fuel sealing between the injectors and the injector-inserting portions of the delivery pipe which could otherwise be caused by high-pressure fuel, thermal contractions at very low temperatures, or the like.

[ What is claimed is:] [1.] A delivery pipe for supplying fuel to injectors that inject fuel directly into combustion chambers of corresponding cylinders of an internal combustion engine, the delivery pipe comprising:injector-inserting portions in which the injectors are mounted; andmounting portions, comprising at least two first mounting portions and at least one second mounting portion, through which the delivery pipe is mounted to the engine, the at least two first mounting portions being disposed on respective lengths of the delivery pipe that extend outward of outermost ones of the injector-inserting portions in a longitudinal direction of the delivery pipe, the at least one second mounting portion being disposed on a length of the delivery pipe extending between two adjacent injector-inserting portions, and the mounting portions being disposed on sides of the delivery pipe in a zigzag arrangement astride an axis along which the injector-inserting portions are arranged.
