PROBLEM TO BE SOLVED: To surely make lubricating oil flow in/out between a pinion gear and a storage hole of the pinion gear. SOLUTION: In this differential device 7, at least one pinion gear 125 of a pair of pinion gears disposed within a differential case 83 has left and right gear parts 129 and 131 and a shaft part 133 of a small diameter for connecting the gear parts 129 and 131, and the shaft part 133 is provided with an opening 139 for making lubricating oil flow in/out between space 221 between the shaft part 133 and the storage hole 127 for storing the pinion gear 125 and the outside of the differential case 83 on a peripheral wall of the facing differential case 83. |
