Zusammenfassung:	PROBLEM TO BE SOLVED: To clearly regulate a preliminary stroke and a residual stroke when high rotational speeds and full load are applied so as to separate both strokes by acting pressure generated in a damping space on the opening stroke of the valve member, against the opening stroke of a valve member on the residual stroke of the valve member, in the damping space. SOLUTION: A damping space 63, in which fuel is filled, is disposed in a fuel injection valve and is restricted by an end surface 41 of a valve member 11, whose diameter is larger than that of a part 61 of a nozzle spindle 39 and an end surface 65 formed on a lower side of an intermediate disk 3 faced to a valve member 11 side. In the damping space 63, pressure generated in the damping space 63 on the opening stroke of the valve member 11 acts against the opening stroke of the valve member 11 on a residual stroke of the valve member 11. The preliminary stroke and the residual stroke are clearly regulated in the case of high rotational speeds and full load, and both strokes are separated from each other.
