Document Type and Number:
Japanese Patent JP4558021
Kind Code:
B2
Abstract:
A fuel injection nozzle for directly injecting fuel into a cylinder of an internal combustion engine is inserted in a connecting pipe 101 extending from a fuel rail 101 and is fixed to the connecting pipe 101 by fastening member 102. The fuel injection nozzle has a sealing part 119 for sealing a fuel passage to prevent fuel leakage, and a contact part 121 in contact with the fastening member 102. The contact part 121 is softer than the fastening member 102, and the contact part 121 undergoes plastic deformation when a bending moment that bends the axis of the fuel injection nozzle acts on the fuel injection nozzle.
