Claims

[Scope of utility model registration request]

a plunger block, a plunger that is slidably attached to the plunger block in the axial direction and has a lead curved in the circumferential direction, and a discharge hole that can be fitted externally to the opposite plunger and aligned with the lead of the plunger. The sleeve is provided with a perforated sleeve and a plunger drive mechanism that can drive the plunger in the axial direction, and a sleeve rotation mechanism that rotates the sleeve to adjust the fuel injection timing. A fuel injection device characterized in that a guide groove is formed along the circumferential direction, a knob that fits into the guide groove, and an eccentric knob moving mechanism that moves the knob in the axial direction. pump.
