A partition structure of a power train device is provided with: a second differential coupled with an external first differential so as to receive a driving force input to the first differential; a case having a first end facing to the first differential, a second end opposed to the first end and a wall defining the case, the case rotatably housing the second differential and an oil for lubrication of the second differential; and a seal member disposed at the first end of the case and between the first differential and the second differential so as to prevent the oil in the case from mixing with an external fluid existing outside with respect to the case and the seal member.

Partition structure of power train device

A limited slip differential is provided with a rotatable casing for receiving input from an engine, a differential gear set of a bevel gear type and a pair of clutches. The differential gear set is provided with a pinion shaft supported in and rotated with the casing, a pinion gear rotatably supported by the pinion shaft and a pair of side gears for output, each of the side gears including gear portion engaged with the pinion gear. The gear portions are exposed to an internal surface of the casing so as not to obstruct oil circulation. The clutches are formed between the side gears and the casing and configured to frictionally transfer torque between the side gears and the casing.
