摘要： A vehicle drive device includes a rotating electrical machine, transmission mechanism, and inverter device. The rotating electrical machine and a pair of output members have a two-axis configuration. The transmission mechanism includes, coaxially with the output members, an output gear drivingly connected to the output members. A first output member is between the rotating electrical machine and inverter device horizontally in an up-down direction where both the rotating electrical machine and inverter device are disposed. The output gear overlaps each rotating electrical machine and inverter device as viewed in an axial direction. The inverter device is on the opposite side of the first output member from the rotating electrical machine and above the first output member. A case includes a peripheral wall portion that separates the first output member and the inverter device from each other. The peripheral wall portion overlaps the output gear as viewed in the axial direction.

摘要： A case (1) that houses a rotary electric machine (2) and an inverter device (INV) has an inlet (11) through which coolant flows, and a channel (4) along which the coolant flows. The channel (4) includes a first heat exchange portion (41) where heat is exchanged between the inverter device (INV) and the coolant, and a turbine disposition portion (43) where a turbine (7) is disposed. The turbine (7) is rotated by a flow of the coolant passing through the turbine disposition portion (43), and a pump rotor (88) of an oil pump (8) that discharges oil to be supplied to the rotary electric machine (2) is drivingly connected to the turbine (7).

摘要： A blade portion that rotates integrally with a target shaft portion is provided between a target outer peripheral surface that is an outer peripheral surface of the target shaft portion and a tubular inner peripheral surface of a case. A first opening that communicates with a first oil passage is located away, on a first axial side, from a second opening that communicates with a second oil passage. The first oil passage communicates with an oil reservoir. The second oil passage communicates with a target space to which oil is supplied. Assuming that a forward rotation state is a rotation state of each part when a wheel is rotating in a direction in which a vehicle moves forward, the blade portion force-feeds the oil to a second axial side when the target shaft portion is in the forward rotation state.
