摘要： A hybrid drive apparatus includes: a drive power source that includes an internal combustion engine, a first electric motor, and a second electric motor; a power transmission mechanism that includes a carrier, a sun gear, and a ring gear, and that is configured to rotate the output shaft of the internal combustion engine by the first electric motor; and plural bearings that each includes an outer ring member and an inner ring member fitted to the outer ring member through a rolling element, and that are provided apart from each other in an axial direction of the output shaft with the carrier being positioned between the bearings. An inner periphery of the outer ring member is positioned more inward in a radial direction of the ring gear relative to a meshing portion between inner teeth of the ring gear and outer teeth of one of the pinion gears.

摘要： In a lubrication structure of a differential gear unit, a case has a guide rib that extends over a certain area with respect to a rotation path of a head of a bolt when a ring gear rotates, and that protrudes out from the case toward the head of the bolt. Also, a through-hole that extends in a vertical direction is formed in an upper portion of a hollow supporting portion, and the guide rib has an oil reservoir that curves toward an upper end opening of the through-hole.

摘要： A lubricating oil supply apparatus arranged in a transaxle case includes a differential ring gear, a catch tank that stores lubricating oil picked up by the differential ring gear, a first flow path arranged higher than a highest position of an outer diameter of the differential ring gear, a gear with a higher center position than the differential ring gear, and a second flow path that guides the lubricating oil picked up by the gear to the catch tank. The first flow path guides the lubricating oil picked up by the differential ring gear to the catch tank. The gear is in mesh with the differential ring gear, and picks up the lubricating oil picked up by the differential ring gear. The second flow path is arranged lower than a highest position of an outer diameter of the gear.
