In order to improve the durability of a bearing that supports a first power transmission shaft in a rotatable manner with respect to a case member, an FF hybrid power transmission device is equipped with: a rotor shaft (6); a transmission input shaft (8); a rear bearing (23); and a bushing support part (24). The transmission input shaft (8) is inserted into and connected to a shaft center aperture part of the rotor shaft (6) via a spline fitting part (22), with power being transmitted between the transmission input shaft and the rotor shaft (6). The rear bearing (23) is interposed between the rotor shaft (6) and a unit case (1), supporting the rotor shaft (6) in a rotatable manner with respect to the unit case (1). The bushing support part (24) is interposed between the rotor shaft (6) and the transmission input shaft (8), and is a radial contact support part that is arranged at an inner circumferential side of the rear bearing (23), at a position that is shifted in the axial direction from the spline fitting part (22). |
