| 1. A fuel injection nozzle for injecting fuel directly into a cylinder of an internal combustion engine, inserted in a fuel
rail and fastened to the fuel rail with a fastening member, said fuel injection nozzle having:
a sealing part for sealing a fuel passage to prevent fuel leakage; and
a contact part in contact with the fastening member;
wherein the contact part is softer than the fastening member, and the contact part undergoes plastic deformation when a bending
moment that bends the axis of the fuel injection nozzle acts on the fuel injection nozzle.
