摘要： A nozzle body with fuel injection holes, a valve guide, a valve body, a movable element and a stopper are provided by low-temperature nitriding treatment at a temperature of 350 through 480° C. A guide sleeve for guiding the movement of a movable element is press-fitted on the inner periphery of the tip of the stationary core, and the guide sleeve is made of a nonmagnetic member of high hardness and provided with a hard coating. A annular-chip valve guide and guide holder are arranged one on top of the other in the nozzle body. This guide holder is composed of a metallic material not provided with nitriding treatment. This guide holder is subjected to plastic deformation in the nozzle body by the pressure from above, whereby the guide holder is pressure-bonded on the inner periphery of the nozzle body, and the valve guide is secured by the guide holder.
