The case and the plunger that reciprocates in the axial direction of the core constitute a magnetic circuit, and a plurality of circumferential grooves are opened toward the center of the circumferential groove provided between the guide portion of the inner diameter of the nozzle and the conical seat surface. In an electromagnetic fuel injection valve, the fuel entering from the plunger is controlled by the reciprocating motion of the plunger, the fuel is swirled by a swirl tip provided in the downstream furnace, and the fuel is metered and injected by an orifice. The structure of an electromagnetic fuel injection valve is characterized in that a member having an orifice for measuring fuel is attached separately from a nozzle having a seat surface. -2 Utility Model Registration The structure of an electromagnetic fuel injection valve according to claim 1, characterized in that the member that combines the swirl tip and the orifice is of a screw type.
