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.

Abstract: A drive unit includes a rotary electric machine; an inverter used to control the rotary electric machine and a capacitor that smooths a power supply voltage of the inverter; and a case housing the rotary electric machine. A control equipment housing space structured by an inverter housing space portion that houses the inverter and a capacitor housing space portion that houses the capacitor is formed in the case on an outer side of the rotary electric machine in an axial center radial direction of the rotary electric machine. A refrigerant flow chamber through which a refrigerant flows is formed between the control equipment housing space and the rotary electric machine. A capacitor heat exchange fin that performs heat exchange between the capacitor housing space portion and the refrigerant is provided between the capacitor housing space portion and the refrigerant flow chamber.
