Abstract
A drive device includes a rotating electrical machine; a control device that controls the rotating electrical machine; and a case that accommodates the rotating electrical machine and the control device. The case includes a machine chamber that accommodates the rotating electrical machine, and an electric chamber that accommodates the control device. The machine chamber and the electric chamber are separated from each other by a partition wall, and a connection member that electrically connects the rotating electrical machine and the control device to each other is provided so as to extend through the partition wall in a fluid-tight state. Each of the machine chamber and the electric chamber has an opening on one axial end side of the rotating electrical machine, and a cover that covers the openings in a separated state from each other is mounted to the openings.
