ELECTROMAGNETIC FUEL INJECTION VALVE

In an electromagnetic fuel injection valve, a plurality of recess parts are provided in an attracted face of a movable core, the recess parts dividing a taper face of the movable core into a plurality of sections along a peripheral direction of the movable core. Accordingly, a fuel oil film present in an engaged part between an annular projection of a fixed core and the taper face is sectioned at a plurality of locations, thereby suppressing a sticking phenomenon of the engaged part caused by the fuel oil film. Therefore, when energization of a coil is cut off, a delay in detachment of the movable core from the fixed core is eliminated, thus contributing to improvement of valve-closing responsiveness.
