PROBLEM TO BE SOLVED: To provide a fuel injection valve having two movable cores and a function of making the lift of a needle variable by regulating an axial displacement of one of the movable cores by the other movable core and improving the productivity. SOLUTION: The fuel injection valve comprises a cylindrical member 18 serving as a casing, the needle 30 provided in the casing, separating from and seating to a valve seat 14, the first movable core 50 axially displaceable along with the needle, the second movable core 60 regulating the displacement of the first movable core and axially displaceable, a drive coil capable of applying magnetic force to the first and second movable cores and a magnetizing member 17, 80 as an attraction member for attracting the second movable core, wherein the lift of the needle is made variable by making the displacement of the first movable core variable. The fuel injection valve comprises a housing 15 which is provided in the casing, receives and unitizes the second movable core and a magnetizing member 18. COPYRIGHT: (C)2006,JPO&NCIPI
