射弁。 An electromagnetic type having one fuel injection hole that measures the injected fuel, and a plurality of injection fuel passages located downstream of the fuel injection hole that branch the fuel from the fuel injection hole in a predetermined direction and inject it from the outlet. In the fuel injection valve,
The wall surface of the passage from the seat part located upstream of the fuel nozzle hole that controls the supply of fuel to the fuel nozzle hole to the fuel nozzle hole is convex toward the inside of the passage and has a curvature that is more than a simple chamfer. An electromagnetic fuel injection valve characterized by being formed into a smooth curved surface with a radius.
