Abstract
A fuel injection valve includes: a valve member; an anchor configured to be relatively displaceable in a valve opening-and-closing direction with respect to the valve member; a fixed core; a first spring biasing the valve member in a valve closing direction; a second spring biasing the anchor in the valve opening direction from an opposite side of the fixed core; and a third spring biasing the anchor in the valve closing direction from the fixed core side and has a biasing force smaller than a biasing force of the first spring and larger than a biasing force of the second spring where engagement portions are provided in both the anchor and the valve member to be engaged with each other when the anchor is displaced in the valve opening direction with respect to the valve member, thereby regulating the displacement of the anchor in the valve opening direction.
