Abstract
An electromagnetic fuel injection valve wherein a movable core disposed opposing an attracting face of a fixed core is slidably fitted onto a stem forming a valve body together with a valve part operating in cooperation with a valve seat, a valve-open side stopper is fixed to the stem so that, by making the movable core, that is attracted to the face when energizing a coil, abut against this stopper, the body is operated to open, and a valve-closed side stopper is fixed to the stem further on the seat side than the other stopper so as to restrict a stroke of the movable core between these stoppers. At least an end part of one of the valve-closed side stopper and the movable core, the end part being on a side of the other one thereof, is formed to gradually decreasing its cross-sectional area in going toward the other one.
