<P>PROBLEM TO BE SOLVED: To provide mounting structure of a fuel injection nozzle, suitable in attachment retention property, while improving ease of work of assembling and removing the fuel injection nozzle to/from an intake passage. <P>SOLUTION: In the mounting structure of a fuel injection nozzle supplying fuel into a combustion chamber of an internal combustion engine, a plurality of protruded claw parts 133 arranged at equal intervals are disposed to a tip part 130 of the fuel injection nozzle, seal packing 121 is disposed to a fuel injection nozzle body part 120, and an assembly hole recess part 72 having a shape corresponding to the plurality of protruded claw parts is formed to the assembly hole part 50. The tip part 130 of the fuel injection nozzle has a slit for allowing deflection in a radial direction. On the other hand, the assembly hole recess part 72 seen from an insertion direction has a shape of which a radius is changed in the radial direction. <P>COPYRIGHT: (C)2011,JPO&INPIT |
