Abstract
A fuel injection valve having a variable stroke mechanism is constructed. A valve body provided to be slidable; a first movable element for cooperating with the valve body; an inner fixed iron core provided at a position to oppose a second movable element; an outer fixed iron core; and a coil are included. A lift amount of the second movable element is set larger than a lift amount of the first movable element, and a portion of the second movable element is projected into the first movable element. In this way, large and small lifts are constituted by using a difference between magnetic attractive forces that are generated in the first movable element and the second movable element by a current supplied to the coil.
