PROBLEM TO BE SOLVED: To provide a differential device capable of surely supplying lubricating oil to a slide surface with each pinion gear of a pinion shaft with a simple configuration. SOLUTION: A differential device includes lubricating oil paths 10, 10 linearly passing through the inside inclined by a specified angle with respect to an axial line m at both axial ends of a pinion shaft 93. While one end of each lubricating oil path is opened outward of a differential case 91 in an axial end corner portion of the pinion shaft corresponding to the upstream side in a rotational direction of the differential case 91, the other end is opened to a slide surface 932 with a pinion gear 94. The lower portion of the differential case is dipped in the lubricating oil O stored in the bottom of a transaxle case 11. The lubricating oil in the bottom of the transaxle case is introduced from one end of each lubricating oil path during rotation of the differential case and then supplied to a slide surface with the pinion gear of the pinion shaft from the other end.
