摘要： An assembling method of a fuel injection valve for fuel injection into an internal combustion engine, the fuel injection valve including a cylindrical valve body having a fuel passage therein and a through-hole made in a direction of the axis thereof and a cylindrical nozzle coupled to the valve body and having a plurality of injection holes for dividing the fuel exited from the through-hole into a plurality of parts and for injecting the divided fuel parts into the engine. The assembling method comprises the steps of coupling the nozzle to the valve body, rotating the valve body relative to the nozzle, and stopping the rotation of the valve body when the through-hole takes a desirable position relative to the injection holes and fixedly securing the nozzle to the valve body. Preferably, an end portion of the valve body is tapered conically and the nozzle has at least one edge portion at its inside so that the edge portion comes into contact with the tapered portion when the nozzle is coupled to the valve body, the edge portion being made of a material whcih is deformed non-elastically in response to application of a force. The edge portion is crushed flat when the nozzle is coupled to the valve body.
