摘要： A case for a vehicle drive device includes a first case part having a first support part, a second case part having a first part, and a third case part having a second part. The second case part is joined to the first case part on an axial-direction first side, the third case part is joined to the first case part on an axial-direction second side, a first rotating body and a first input member are placed between the first support part and the first part in an axial direction, in a supported state by the first support part and the first part, and a second rotating body and a second input member are placed between the first support part and the second part in the axial direction, in a supported state by the first support part and the second part.

摘要： A vehicle drive device is provided that can suppress the increase in dimension in the radial direction while ensuring a sufficient speed reduction ratio. Two driving force sources are arranged on a first axis, two output members are arranged on a second axis, two counter gear mechanisms are arranged on a third axis. A planetary gear mechanism is configured to transmit rotation from the two counter gear mechanisms to the output members, and is disposed so as to overlap with both of the two counter gear mechanisms as seen in an axial direction along and axial direction.

摘要： A left-right wheel driving device (10) includes: a casing (15) including a reservoir (18) that stores oil; a suction port (19) that is disposed on the reservoir (18) and that sucks the oil from the reservoir (18); and two gears (34) that are each having helical teeth, that are supported so as to be rotatable about a rotating shaft (13) at least in one direction (D), that are provided on a power transmission path that transmits power to left and right wheels of a vehicle, and that are spaced apart from each other. The suction port (19) is positioned between the two gears (34). Each of the gears (34) is offset from the suction port in an axial direction of the rotating shaft (13), being in a state of being partially immersed in the oil stored in the reservoir (18). The helical teeth of each of the gears (34) extend in the one direction (D) and in a direction that departs from the suction port (19).
