  "textContent": "A fuel injection valve (1) configured such that control of the escape of high-pressure fuel inside a control chamber (45) to a fuel low-pressure portion is conducted by an electromagnetic valve (5) for controlling fuel injection configured such that a lift operation of an armature plate (51) is controlled by an electromagnetic solenoid (68) and an armature stopper (67) incorporated inside a fixed sleeve (61), wherein a gap (G3) is disposed between a fixed core (63) and the armature stopper (67), through holes (67B) are disposed in the armature stopper (67), and drain fuel flows to the fuel low-pressure portion via the gap (G3) and the through holes (67B) when the electromagnetic valve (5) is powered. As a result, the lift amount of the armature plate (51) can be prevented from changing as a result of debris or the like included in the drain fuel becoming caught between the armature plate (51) and the armature stopper (67).",
