Fuel injection valve for internal combustion engine

A fuel injection valve for an internal combustion engine, comprising:

• a valve housing that includes an injection hole, which is configured to inject fuel in the internal combustion engine;
• a valve member that is configured to reciprocate between a valve opening side and a valve closing side, which are opposite to each other in an axial direction, to respectively open and close the injection hole;
• a stationary core that is fixed to the valve housing;
• a movable core that is movable together with the valve member, wherein the movable core moves toward the valve opening side when a magnetic force is exerted between the stationary core and the movable core;
• a magnetic spring that is made of a magnetic material, wherein the magnetic spring is held by the stationary core and urges the valve member toward the valve closing side;
• and
• a solenoid device that is held on a radially outer side of the stationary core and generates the magnetic force by guiding a magnetic flux to the stationary core and the movable core in response to energization of the solenoid device, wherein:
• the stationary core includes a holding hole that receives and holds a portion of the magnetic spring, which is located on the valve opening side;
• and
• the solenoid device includes a magnetic yoke that extends in the axial direction and has an axial extent, which overlaps with an entire axial extent of the holding hole, wherein the magnetic yoke has a predetermined portion that reduces an amount of the magnetic flux, which passes through the magnetic yoke in a radial direction, in comparison to the rest of the magnetic yoke.
