Abstract
A lubricating structure for a differential device includes a pair of baffle plates, fixed to a transmission case, partitioning an internal space between the transmission case, and a differential case and a final driven gear and a second space. The inner surface of the baffle plates has a portion on the first space side that is enlarged to be similar in shape to outer surfaces of rotating bodies defined by trajectories of the differential case and the final driven gear rotated around a rotational axis of inboard shafts. The baffle plates are configured such that the amount of lubricating oil accumulating in the first space is smaller than that in the second space. A through-hole is provided at a position to secure a level of lubricating oil.
