Abstract:
1. A vehicular power transmission device comprising: a casing; a differential device of a planetary gear type housed in the casing; an input shaft that transmits power to the differential device; and a first output shaft and a second output shaft to which the power from the input shaft is output via the differential device; wherein the differential device includes a carrier, a sun gear, and a ring gear such that the carrier is coupled to the input shaft, the sun gear is coupled to one end of the first output shaft, and the ring gear is coupled to the second output shaft, the first output shaft and the second output shaft are disposed coaxially in series on an axis with the differential device interposed between the first output shaft and the second output shaft, an other end of the first output shaft is supported in a direction of the axis by the casing via a first thrust bearing that supports thrust force which is directed toward the other end of the first output shaft, the second output shaft is supported in the direction of the axis by the casing via a second thrust bearing that supports thrust force which is directed from a first output shaft side toward the second output shaft, thrust force of the sun gear is supported by the first thrust bearing via the first output shaft, and thrust force of the ring gear is supported by the second thrust bearing.
