A power transmission apparatus is capable of easily passing lubricant toward a seal arranged between a higher shat and an opening of a case of the apparatus. The apparatus includes the higher shaft, i.e., a hollow connecting shaft that faces the outside of the transfer case through the opening of the transfer case. The oil seal is arranged between the hollow shaft and the opening of the transfer case. The hollow shaft meshes, through helical spur gears, with an intermediate transferring shaft that is positioned lower than the hollow shaft. A lubricant guide is arranged to receive lubricant splashed up by the ring gear and helical spur gear of the intermediate shaft and guide the received lubricant toward the oil seal and a ball bearing.

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.
