PROBLEM TO BE SOLVED: To provide a fuel injection pump lubricating structure capable of reducing cost, and capable of improving assembling performance, by reducing the number of part items, while improving reliability against external leakage of lubricating oil by setting a seal surface in one place, in a constitution for lubricating by sending the pressurized lubricating oil from a lubricating oil pump provided in an engine to a driving part of a fuel injection pump. SOLUTION: This fuel injection pump lubricating structure is constituted for directly connecting a fuel injection pump 8 to a cylinder block 2 by projecting an installation part flange of the fuel injection pump 8 from one side of the cylinder block 2, and has a lubrication hole 32 reaching the driving part of the fuel injection pump 8 formed by penetrating through the installation part flange, a main gallery 31 formed in the cylinder block 2, and a communicating member 33 communicating the lubrication hole 32 with the main gallery 31.
