Abstract
Official abstract text for this publication.
A metal valve body having a fuel injection port includes a nozzle plate accommodation part accommodating a nozzle plate of synthetic resin and aligning a center of the nozzle plate with a central axis of the valve body. A front end surface abutting against the nozzle plate is accommodated in the nozzle plate accommodation part. A swage projection fixes the nozzle plate to the front end side on which the fuel injection port is formed. The nozzle plate is swage-fixed in the state in which a spring action part is elastically deformed on the front end side of the valve body by the swage projection, and a nozzle hole formation part is constantly pushed against the front end surface of the valve body by the elastic force of the spring action part.
