PROBLEM TO BE SOLVED: To reduce a dragging loss when advancing a vehicle by using only second rotary electrical machinery.SOLUTION: A vehicle driving device includes first rotary electrical machinery 11, an intermediate output rotation member 51 provided between the first rotary electrical machinery and a wheel 2, second rotary electrical machinery 12 driven by-connected to the first rotary electrical machinery via the intermediate output rotation member and driven by-connected to the wheel, and a first one-way clutch provided between the intermediate output rotation member and a first rotary electrical machinery output member being an output member of the first rotary electrical machinery, becoming free when the intermediate output rotation member relatively normally rotates to the first rotary electrical machinery output member when setting the rotational direction when a vehicle advances as the normal direction, and engaging when the first rotary electrical machinery output member relatively normally rotates to the intermediate output rotation member.SELECTED DRAWING: Figure 1 |
