Abstract
A lubrication structure of a hybrid vehicle includes a gear chamber that houses a planetary gear unit and a differential device, and a motor chamber that houses a rotating electric machine, and is separated from the gear chamber by a partition wall. Lubricating oil stored in a bottom portion of the gear chamber is stirred up through rotation of a final reduction gear of the differential device disposed in a lower portion of the gear chamber, so that the lubricating oil is supplied to the planetary gear unit. One end of a cylindrical output member of the planetary gear unit is rotatably supported by a partition wall via a bearing, and a communication hole that communicates the gear chamber with the motor chamber is provided in an opposed portion of the partition wall which is opposed to a vicinity of an outer peripheral edge of the bearing.
