Abstract
A wheel assembly with an in-wheel motor in which a wheel driving apparatus formed of a motor or a combination of a motor and a reduction mechanism is provided in a wheel, includes an oil supply apparatus that is driven by rotational output of the motor, and an oil supply flow path that leads oil that has been drawn up by the oil supply apparatus to the wheel driving apparatus. The oil supply apparatus is structured so that oil can be supplied to the wheel driving apparatus via the oil supply flow path when the motor is rotating in the forward direction as well as when the motor is rotating in the reverse direction.
