A hybrid vehicle including an engine, a drive motor, a first oil pump, and a second oil pump is configured to, during forward travel, supply components to be cooled or lubricated with oil discharged from a discharge port of the first oil pump and a discharge port of the second oil pump via an oil passage, while the hybrid vehicle is configured to, during reverse travel, compensate for a driving force by supplying oil discharged from the discharge port of the second oil pump to the discharge port of the first oil pump via the oil passage to cause the first oil pump to operate as a hydraulic motor.

Hybrid vehicle

A power transmission device for a vehicle includes a support member; a first bearing rotatably supporting a first rotation shaft with respect to the support member; a second bearing, provided adjacent to the first bearing, rotatably supporting a second rotation shaft with respect to the support member, the second rotation shaft being rotated around an axis line same as an axis line of the first rotation shaft; and a partition wall formed in the support member and including a notch. Further, the support member includes an oil gallery to supply lubricating oil into a space formed between the first bearing and the second bearing, the space is partitioned into a first space on a side of the first bearing and a second space on a side of the second bearing by the partition wall, and the oil gallery is formed to eject the lubricating oil toward the notch.
