Original Abstract Submitted

a differential device includes: a pinion gear; a pinion shaft for rotatably supporting the pinion gear; a pair of side gears, which engage with the pinion gear and are fitted to a pair of drive shafts; a differential case, which supports the pinion shaft, houses the pinion gear and the side gears, and has an opening on one side of the drive shafts; and a differential cover, which has a hole through which one of the drive shafts penetrates, is fixed to the differential case, and closes the opening. further, the differential cover has an oil passage which penetrates along the hole from an inner surface facing the side gears to an outer surface opposite to the differential case and through which a lubricating oil flows.
