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 bodymanufactured by forging, the rail bodyhaving a through holeopened on a wall surfacefor communicating a fuel passageextending in an axial direction with an outside; and a tubular joint membermanufactured separately from the railbody and fixed to the rail bodyat a position of the through holefor allowing a fuel to flow from the fuel passagethrough the through holeare provided.
