A lubricating device of a differential gear is provided to increase a lubricating amount by spraying oil using a centrifugal force by implementing a spraying diaphragm on a pinion rotation axis of the differential gear. A differential gear(1) includes a pinion gear shaft(3), a pinion gear(4), and left/right side gears(6,7). The pinion gears are mounted at both ends of the pinion gear shaft. The left/right side gears are mated with the pinion gear. An oil spraying diaphragm(8) sprays the oil, which is collected on the pinion gear shaft, using a centrifugal force. The oil spraying diaphragms are implemented to be symmetrical with respect to each other with the pinion generator shaft between them. The oil spraying diaphragm is mated with the pinion gear shaft using a convexo-concave interface.
