Abstract
A tubular rail body has an inlet for introducing a fuel therein from a fuel supply source. A plurality of tubular protrusion portions project from the rail body in a substantially vertical direction relative to an axial direction of the rail body, and are arranged at a predetermined interval in the axial direction. A tubular extension portion extends from each of the protrusion portions in a substantially vertical direction relative to both an axial direction of the protrusion portions and the axial direction of the rail body. The tubular extension portion is inserted into a bore which extends from an exterior of an internal combustion engine to a combustion chamber. A connecting portion is formed on an end portion of the extension portion opposite to the protrusion portion and is fluidly connected with a fuel injector inserted in the bore.
