Abstract
The flexibility of the attachment angle and attachment interval of the member (e.g., injector) attached to the joint member is increased to improve the flexibility of layout even in the case of the forged rail for high-pressure direct injection. In addition, the manufacturing cost can be reduced while keeping high strength of the joint portion. A rail body 1 manufactured by forging, the rail body 1 having a through hole 4 opened on a wall surface 3 for communicating a fuel passage 2 extending in an axial direction with an outside; anda tubular joint member 6 manufactured separately from the rail 1 body and fixed to the rail body 1 at a position of the through hole 4 for allowing a fuel to flow from the fuel passage 2 through the through hole 4 are provided.
