Title: DIFFERENTIAL DEVICE
Abstract:
A differential device comprising: a differential gear mechanism comprising a plurality of differential gears, a plurality of differential gear support bodies that support the plurality of differential gears, and a pair of output gears that engage with each of the differential gears; and a differential gear case comprising a support member having a plurality of both-end support sections that support both ends of each of the differential gear support bodies, a first cover member that covers the rear surface of one of the output gears and can couple with the support bodies, and a second cover member covering the rear surface of the other output gear and can couple with the support bodies. A recessed section (81o) that faces the rear surface (30f) of each differential gear (30) is formed in an outer support section (81) supporting one end section of the differential gear support body (33) on the outside in the radial direction in the output gears (31, 32), of each both-end support section (8). In each outer support section (81), the axial direction side of the output gears (31, 32) is covered by the second cover members (21, 22). As a result, lubrication performance of the rotating sliding surface between the differential gear rear surface and the differential gear case is improved.
