Abstract
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.
