摘要： PROBLEM TO BE SOLVED: To provide a common rail withstanding a high fuel injection pressure, manufacturable at low cost, and having high productivity in the common rail which is a component of an accumulator fuel injection system for a diesel engine. SOLUTION: An orifice tube 3 is installed in a flow passage extending from the boundary part between the rail hole 11 and the branch hole 12 of a common rail body 1 to an injection tube 2 connected to an injection nozzle. A residual compressive stress is applied to the peripheral part of one or both of two openings 21a, 21b of the orifice tube 3 by laser peening for increasing the fatigue strength. Since the strength of the orifice tube 3 itself is suppressed, a high pressure common rail manufacturable at low cost and having high productivity while maintaining the working efficiency of the orifice tube 3 is provided.
