Patent attributes
An electromagnetic fuel injection valve in which a first resin-molded layer that is made of a synthetic resin, covers a solenoid section, and forms a coupler main portion that defines a coupler is covered by a second resin-molded layer different from that of the first resin-molded layer so that an outer face of the coupler main portion is exposed from a middle part up to the extremity of the coupler main portion. An endless engagement groove is provided on the outer periphery of the middle pad of the coupler main portion of the first resin-molded layer, the second resin-molded layer engaging with the endless engagement groove. An extending portion extending further outward than the engagement groove is formed in the second resin-molded layer so that the extending portion makes contact with an outer face of the coupler main portion when in a non-engaged state and covers the coupler main portion.
