とする燃料噴射ポンプのタイマ潤滑装置。 A fuel injection pump connected to a cylinder block of an internal combustion engine so that power from a crankshaft can be taken out via an idle gear in a gear case, a gear case cover that covers an open end surface of the gear case, and a fuel injection penetrating the gear case and the gear case cover. In a fuel injection pump consisting of a timer assembly fixed to the end of the camshaft of the pump, an inflow side lubricating oil passage with one end open is formed on the outer circumferential surface of the idler shaft that pivotally supports the idler gear, and An outflow lubricating oil passage is provided at one end on the outer circumferential surface and communicating with the pipe joint bolt that fixes the gear case cover to the idle shaft, and both of the lubricating oils are supplied to the approximately cylindrical idle gear bush fixed to the idle gear. A timer-side pipe joint that forms a window hole that intermittently communicates the open end of the passage, penetrates the idle shaft-side pipe joint bolt and a timer cover that covers the timer assembly, and injects lubricating oil to the timer assembly. A timer lubricating device for a fuel injection pump, characterized in that a lubricating oil pipe is provided that communicates between the bolt and the lubricating oil pipe.
