FUEL INJECTION VALVE

PROBLEM TO BE SOLVED: To provide a fuel injection valve preventing a gap between a movable core and a fixed core from changing when a load adjusting member is installed by press fitting. SOLUTION: A pipe member 30 is inserted in an inner circumference wall on an opposite side of a valve body 12 of a valve housing 16 and is fixed to the valve housing 16 by welding. A fixed core 50 is press-fitted in the pipe member 30 on an opposite side of an injection hole 13 in relation to a movable core and faces to the movable core 40. An inlet member 52 is installed on an opposite side of the movable core in relation to the fixed core 50 and separately from the fixed core 50. An adjusting pipe 56 is press-fitted in the inlet member 52 and is inserted on an inner circumference side of the fixed core 50 with a gap 200 formed from the fixed core 50. Load of a spring applied to the movable core 40 and a nozzle needle 20 is adjusted by adjusting press fitting quantity for press fitting an adjusting pipe 56 in the inlet member 52.
