Abstract
A stationary core includes a holding hole that receives and holds a portion of the magnetic spring, which is located on a valve opening side. A solenoid device includes a magnetic yoke that extends in an axial direction and has an axial extent, which overlaps with an entire axial extent of the holding hole. The magnetic yoke has a predetermined portion, which reduces an amount of the magnetic flux that passes through the magnetic yoke in a radial direction in comparison to the rest of the magnetic yoke.
