Abstract
A drive device includes an input shaft connected to an engine; a first rotating electrical machine and a second rotating electrical machine; a differential gear unit including a first rotating element, a second rotating element, and a third rotating element; and a control device. The first rotating electrical machine and the differential gear unit are positioned coaxially with the input shaft. The first rotating electrical machine and the second rotating electrical machine are positioned on different axes from each other so as to axially overlap each other. A first component of the control device is positioned lower than the first rotating electrical machine and positioned so that at least a part of the first component overlaps the first rotating electrical machine when viewed in a vertical top plan view.
