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).
