Abstract
The drive device includes a first motor, a first gear mechanism, a second motor, a second gear mechanism, and a casing. The casing has a first gear chamber for accommodating the first gear mechanism, a second gear chamber for accommodating the second gear mechanism, and a partition wall interposed between the first gear chamber and the second gear chamber. The first gear chamber and the second gear chamber are arranged in a right-left direction of the vehicle, with the partition wall interposed therebetween. The partition wall is provided with a first communication passage that allows lubricating liquid retained in a lower portion of the first gear chamber to flow to the second gear chamber, and a second communication passage that allows lubricating liquid retained in a lower portion of the second gear chamber to flow to the first gear chamber, independently of each other.
