<P>PROBLEM TO BE SOLVED: To provide a high-pressure fuel injection pipe having a joint structure for suppressing occurrence of bending stresses caused by deviation of the axis and efficiently improving sealability for higher pressure. <P>SOLUTION: This high-pressure fuel injection pipe 1 having a joint structure to lead a high-pressure fuel to a fuel injector 100 of an internal combustion engine comprises a cap nut 10 to be screwed to the fuel injector 100 and a tip part 22 which is passed in the cap nut 10 in a locking manner and connected to an object 102 having a conical surface of the fuel injector 100, and a locking part 22b having a substantially spherical surface 22bc abutted in the cap nut 10 is provided on the tip part 22. <P>COPYRIGHT: (C)2004,JPO |
