A vehicle differential (10,48,54,60) includes a pair of side gears (18), a pinion gear (20), a differential case (26), and an annular ring gear (28,50,56,62). At least one opening (36) is arranged through a peripheral wall (22) of the differential case (26). The annular ring gear (28,50,56,62) is fitted on the outer side of the peripheral wall (22). The annular ring gear (28,50,56,62) includes a protrusion (44, 52, 58, 64) on an inner peripheral edge of the annual ring gear (28,50,56,62). The protrusion (44,52,58,64) covers a part of the opening (36) in a view along a penetration direction of the opening (36). The protrusion protrudes toward the inner side of the opening (36) in the radial direction of the rotational axis as compared with other parts of the inner peripheral edge of the annular ring gear which have no protrusion. |
