Abstract: The present invention addresses the problem of preventing engine start faults caused by moisture adhering to a control rack of a fuel injection pump and the moisture freezing. This fuel injection pump (1) installed in a diesel engine (30) is provided with: a control rack (20) which is disposed in a rack chamber (5) formed between a pump head (3) and a pump housing (2), and adjusts the fuel injection amount; a transmission shaft (49) rotatably supported in a transmission shaft hole (2C) formed in the pump housing (2); and a lubricant passage (2D) which is formed in the pump housing (2) and forcibly feeds a lubricant between the transmission shaft (49) and the transmission shaft hole (2C). An oil path (40), through which a portion of the lubricant forcibly fed through the lubricant passage (2D) passes, is formed in the transmission shaft (49), a first opening part (41A) of the oil path (40) communicates with the lubricant passage (2D), and a second opening part (42A) of the oil path (40) is formed on the outer peripheral surface of an upper portion of the transmission shaft (49) in the proximity of the control rack (20).

Abstract: A technology that can extend the life of a fuel injection device of an engine while maintaining its good responsiveness is provided. A fuel injection device 100 for an engine includes: a control rack 55 supported to be slidable in an axial direction and capable of adjusting of a fuel pressure-feed amount of a fuel pressure-feed mechanism unit 51, based on its slide-position relative to the axial direction; an actuator 40 capable of reciprocating its operating unit 41; and a link lever 20 swingably supported by a pivot shaft member 25 and configured to swing in association with reciprocation of the operating unit 41 of the actuator 40 thereby causing the control rack 55 to slide, wherein the fuel injection device includes an actuator-side connecting part 20A connecting an operating unit 41 of the actuator 40 to the link lever 20, and the actuator-side connecting part 20A is positioned on the same axis as the operating unit 41 of the actuator 40.
