To provide a wheel drive device capable of suppressing an increase in the temperature of an electric motor and a power converter, and suppressing the occurrence of failure in an electric component.SOLUTION: A wheel drive device includes: an electric motor including a stator 60 and a rotator 40; a stator holding part 80 for holding the stator 60; a power converter 100 for converting power to be supplied to the electric motor; and a wheel for accommodating the electric motor, the stator holding part 80, and the power converter 100 on an inner peripheral side. The stator holding part 80 includes a flow passage 90 through which a refrigerant flows. The flow passage 90 is arranged between the stator 60 and the power converter 100.SELECTED DRAWING: Figure 1
