HOLDER FOR FUEL INJECTOR AND METHOD OF MANUFACTURING THE SAME

摘要

A holder (10) for a fuel injector, wherein a first cylindrical part (12) inserted into a hole part (22) formed in a fuel feed pipe (20), a second cylindrical part (14) formed continuously with the first cylindrical part, disposed projectedly from the fuel feed pipe, and accepting a fuel injector (30) and a flange part (16) formed in a boundary between the first cylindrical part and the second cylindrical part to be swelled in the radial outer direction of the outer peripheral walls of the first and second cylindrical parts and brought into contact with the fuel feed pipe at the peripheral edge of the hole part formed in the fuel feed pipe are formed integrally with each other by press-molding a plate material. Since the wall thickness of the first cylindrical part (12) is formed thinner than that of the second cylindrical part (14) in press-molding, the flange part (16) is formed by the plastically fluidized wall part of the first cylindrical part.
