摘要： An injector used for an internal combustion engine includes a valve needle which closes a fuel passage by contacting a valve seat and opens the fuel passage by separating from the valve seat. A coil and a magnetic core are provided to drive the valve needle, and an anchor is held in a relatively displaceable state with respect to the valve needle. A first biasing device biases the valve needle in a direction opposite to a direction of a drive force, and a second biasing device biases the anchor in the direction of the drive force with a set load smaller than that of the first biasing device. A restricting feature restricts relative displacement of the anchor with respect to the valve needle in the direction of the drive force.
