Abstract:
An electric transaxle according to the invention comprises a transaxle casing, an electric motor, an axle, a gear mechanism, first and second fluid sumps, and first and second fluid introduction passages. The transaxle casing defines a gear chamber therein. The electric motor includes a motor casing attached to the transaxle casing. The axle is supported by the transaxle casing. The gear mechanism transmits power from the electric motor to the axle. Fluid of the first fluid sump raised by driving the gear mechanism is supplied to the second fluid sump. The first fluid introduction passage introduces the fluid raised from the first fluid sump to the second fluid sump when the axle is rotated in a forward traveling direction. The second fluid introduction passage introduces the fluid raised from the first fluid sump to the second fluid sump when the axle is rotated in a backward traveling direction.
