A vehicle drive device that includes a case forming a first accommodating space that accommodates a speed change device and a second accommodating space that accommodates a rotary electric machine; an storage that is disposed under the first accommodating space and stores oil; a hydraulic pump including a suction that suctions the oil from the oil storage; a first oil passage that supplies the oil discharged by the hydraulic pump to the speed change device as hydraulic oil; a second oil passage that supplies the oil discharged by the hydraulic pump to the rotary electric machine as cooling oil; and a third oil passage that returns the oil supplied to the rotary electric machine, from the second accommodating space to the oil storage, by allowing the oil to flow in a direction from the second accommodating space toward the first accommodating space.

Vehicle drive device

A power transmission apparatus includes a first electric motor, a power split mechanism, a second electric motor, a case, a support wall, and a breather mechanism. The case accommodates the first electric motor, the power split mechanism, and the second electric motor. The support wall is provided between the power split mechanism and the second electric motor. The breather mechanism is located in a rotational angle range that is at least equal to 90 degrees and is smaller than 180 degrees. The breather mechanism has a through hole and a breather chamber. The breather chamber is provided at a case inner side end of the through hole and is opened in a direction that does not oppose a virtual surface that passes through the rotational axis at a rotational angle of 90 degrees of the second electric motor.

Power transmission apparatus for vehicle

A lubricating structure for a transmission includes: a case that includes a center support fixation portion that extends from the inner peripheral surface toward the radially inner side, and that houses the transmission on the first side of the center support fixation portion in the axial direction of the transmission; a center support that is press-fitted into the center support fixation portion, that rotatably supports an input shaft of the transmission, and that rotatably supports a clutch drum of the transmission; a bearing provided between the clutch drum and the center support in the axial direction; an oil reservoir portion formed on the center support on the second side of the center support fixation portion in the axial direction to open on the upper side in the vertical direction, the second side being opposite to the first side; and an oil passage formed in the center support, one end of the oil passage opening in the oil reservoir portion, and the other end of the oil passage opening in a space between the clutch drum and the center support in the axial direction.
