<p>To provide a vehicle drive device in which oil does not fall onto a rotor while supplying and discharging the oil to and from a bearing for rotatably supporting the rotor in order to lubricate the bearing, thereby suppressing an increase in device size. A vehicle drive device 1 that includes a rotating electrical machine 3 having a rotor 3b and a stator 3c, and a rotation shaft 2 having a rotation shaft center X includes: a partition wall 11 defining at least a part of a space for accommodating the rotating electrical machine 3; a rotor support member 50 that rotates about the rotation shaft center and supports the rotor; a bearing 61 disposed between the rotor support member and the partition wall; a first seal member 71 that forms a first oil chamber 81 that is in contact with one side end of the bearing; a second seal member 72 that forms a second oil chamber 82 that is in contact with the other side end of the bearing; a supply oil passage 80 for supplying oil to the first oil chamber; and a discharge oil passage 83 for discharging oil from the second oil chamber.</p> |
