Zusammenfassung:	PURPOSE:To certainly and stably position a nozzle against a body both in the axial direction and in the diametrical direction by making a contact part formed on the nozzle contact with a tapered part formed on the body. CONSTITUTION:A cylindrical body 5 with a through hole 5c to derive fuel formed on its one end side and a bottomed cylindrical nozzle 7 with injection holes 8a, 8b formed on its bottom part are furnished. Especially, a tapered part 5d formed on the outer periphery of the one end side of the body 5 is furnished. Additionally, the nozzle 7 is furnished with a contact part, and a protruded part 7c formed on the inside of a cylindrical part of the nozzle 7 to face the tapered part 5d of the body 5 is formed by making it contact with the tapered part 5d and by plastic deforming it. Additionally, by making contact with the tapered part 5d, the nozzle 7 is positioned against the body 5 in the diametrical direction and in the axial direction. Consequently, it is possible to certainly and stably position the nozzle 7 against the body 5.
