Abstract: A differential case has no hole other than two oil holes except for a pinion shaft hole and a pair of drive shaft holes and has an annular receiver attached thereto that has an inner periphery smaller than the outer periphery of side gear washers with respect to the rotation center of the rotation axis of drive shafts and that has an outer periphery located beyond the outermost edge of the oil holes with respect to the rotation center of the rotation axis. This controls the outflow of lubricating oil located radially outward of the inner periphery of the receiver, thus allowing the side gear washers to be supplied with lubricating oil, regardless of whether the differential case is rotating or stops rotating.

Operation of a second clutch transmits from an input shaft to a third ring gear, a third clutch inputs decelerated rotation of the reduction planetary gear to the second sun gear, a fourth clutch transmits from the input shaft to the second carrier, a first brake prevents a second sun gear from rotating, a second brake prevents a carrier from rotating, a third brake capable prevents a third ring gear from rotating.
