- the outflow passage 34 allows the high pressure fuel to flow out from the back pressure chamber 30 to the low pressure side.
- the holder body 4 accommodates an electromagnetic unit 8.
- the electromagnetic unit 8 has a stator 38, and the stator 38 has an electromagnetic coil 36 wound around a resin bobbin.

- the magnetic concentrating member 100 Since the gap between the magnetic flux concentrating member 100 and the inner cylindrical portion 98a near the coil 96 is relatively large, the magnetic concentrating member 100 is directly adjacent to the inner cylindrical portion 98a in the vicinity of the coil 96. The magnetic flux to go can be made rough.
- the outer peripheral portion of the armature 80 extends to a position outside the inner peripheral surface of the magnetic flux concentrating member 100, but does not extend to the outer cylindrical portion 98b. That is, a part of the armature 80 and a part of the magnetic flux concentrating member 100 are overlapped. Further, the lower end of the inner cylindrical portion 98 a is located above the magnetic portion 88 of the armature 80.

- the through-hole 86 that guides the guide pin 102 is formed in the high-strength portion 84, the high-strength portion 84 is not cracked even if the through-hole 86 is formed. Further, as is clear from FIG. 2, these through holes 86 are formed in the high-strength portion 84 away from the portion where the magnetic flux concentrates in the armature 80 when the coil 96 is energized. Thus, the concentration of magnetic flux is not hindered, and the armature 80 moves at a high speed.

- the through hole 86 for guiding the guide pin 102 is formed in the magnetic portion 88 of the armature 80, and the magnetic portion 88 is formed at a position where the magnetic flux from the coil 96 is coarse. Therefore, the magnetic force for attracting the armature 80 is not weakened by the through hole 86, and the armature 80 can be attracted at a high speed from this point.
- the valve portion 82 is formed integrally with the armature 80, the armature 80 does not need to be provided with a contact portion unlike the armature of the prior art, the armature can be reduced in weight, and the armature can be made faster and faster. 80 can be moved.
