Abstract: A vehicle drive device includes a rotating electrical machine, an input shaft including a first gear and connected to a rotor shaft, a counter gear mechanism, a differential gear mechanism, a pair of output members, and a case. The input shaft includes: a first supported portion supported by the case via a first bearing located on a first side in an axial direction with respect to the first gear; a connection portion located on the first side in the axial direction with respect to the first supported portion and connected to the rotor shaft; and a small diameter portion located between the first supported portion and the connection portion and having a diameter smaller than an outside diameter of the first supported portion and an outside diameter of the connection portion.

Abstract: A case body has a first opening that is open along a first direction and through which an inverter device is insertable, a surrounding wall portion disposed along the first direction so as to surround the first opening, and a second opening that is formed in the surrounding wall portion and through which a power cable is insertable. A cover member is fixed to the surrounding wall portion by a plurality of fastening members disposed away from each other along an opening edge of the first opening so as to cover the first opening. A second opening width in a direction orthogonal to the first direction is smaller than an opening width of the second opening in the first direction, and a pair of the fastening members is disposed on both sides across the second opening.

Abstract: A vehicle drive device includes a rotary electric machine, an inverter device, and a case. The case includes a case body and a cover member. The case body is integrally formed so as to form a first housing chamber that houses the rotary electric machine and a second housing chamber that houses the inverter device, and has an opening that is open from the second housing chamber toward an outside of the case. The cover member is disposed so as to cover the opening, and includes a flat plate portion. A sheet-shaped damping member having a function of converting vibration into heat is attached so as to cover at least a part of the flat plate portion.
