PROBLEM TO BE SOLVED: To equally supply oil scraped up by a final driven gear provided on a differential case to right and left bearings, regardless of vehicle speed.SOLUTION: A gutter plate 27 disposed on an upper part of a final driven gear 18 is equipped with a first oil capturing portion 28 opposing to an outer peripheral surface of the final driven gear 18 and extending to one end side in an axial direction, and a second oil capturing portion 29 extending from the first oil capturing portion 28 to the other end side in the axial direction. The first oil capturing portion 28 inclines in an inclining direction of a tooth surface 18a by a predetermined angle &thetas;b when viewed from a diametrical direction of the final driven gear 18, and the second oil capturing portion 29 extends in a generally axial direction when viewed from the diametrical direction of the final driven gear 18. Therefore, by distributing oil scraped up by the final driven gear 18 and colliding with the gutter plate 27 to one end side in the axial direction and the other end side in the axial direction with different ratios, bearings 20 and 21 for supporting both ends in the axial direction of a differential case 15 can be equally lubricated. |
