摘要： PROBLEM TO BE SOLVED: To provide a common rail improving fatigue strength by reinforcing surrounding parts of openings of a plurality of branch holes connected to a cylinder wall part surrounding a rail hole in common rails which are components of pressure accumulation type duel injection systems of diesel engines. SOLUTION: Compression stress is introduced to a boundary circumference part of an inner surface 22 of the rail hole 5 and an inner surface 21 of the branch hole 6 which are the opening circumference part 23 of the branch hole 6, and which causes a problem of fatigue strength in the common rail 1 by laser peening process irradiating pulse laser beam under existence of transparent liquid. Material in an area including a section where laser peening process is applied is removed by method such as electrolyte polishing and liquid polishing and the like after that. Consequently, high compression stress can be introduced to the boundary circumference part from a surface and stress concentration can be relaxed by improving shape of the boundary circumference part.
