PURPOSE: To make an easy and automatic assembly possible by fabricating an assembly in such a way so that each component can be serially inserted. CONSTITUTION: In a fuel injection nozzle 10, the outer components consist of a nozzle main body 12, nozzle cap 14, fuel inlet stud 16 and leak-off cap 18. The nozzle main body 12 has substantially a specific outer diameter except for a shoulder 60. The connection between the main body 12 and fuel inlet stud 16 is performed by tightening a banjo-type fuel inlet stud 16 up to a specific location in a valve chamber 24 on the main body 12 to fit in. Thus, an assembly can be performed in which each of the components needs to be only inserted serially. Complex assembling operations which would involve rotating or radially manipulating against the axis of the nozzle 10 can be eliminated and expenses can be saved because automatic assembling process can be performed. |
