ABSTRACT:
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.
