PROBLEM TO BE SOLVED: To reduce the size of a differential mechanism.SOLUTION: An inner race 41a of a bearing member 41 at one side in an axial direction supporting a differential case 35 is attached to a cylinder part 39 at one side in the axial direction, an outer race 41b is attached to a cylindrical part 49 of a differential case main body 43. An outer peripheral face 51a at one side in the axial direction sandwiching a flange part 45 is located more inside in a radial direction from an outer peripheral face 51b at the other side, a ring gear 19 is arranged at one side in the axial direction of the flange part 45, and an inner peripheral end 19b is located more inside in the radial direction from the outer peripheral face 51b of the other side in the axial direction. A bolt 53 is fastened to the flange part 45 from the ring gear 19 in the axial direction, and a bolt head 53a is located at one side of the ring gear 19 in the axial direction. |
