Provided is an in-wheel motor drive device capable of accurately detecting abnormality in an entire output range of the motor by detecting the temperatures of a lubricating oil and a motor coil. The in-wheel motor drive device comprises an electric motor (1), a vehicle wheel bearing (5), a speed reducer (2), a lubricating oil supply mechanism (Jk), and a control device (U1). An oil temperature sensor (Sb) is provided in a lubricating oil path (29) of the speed reducer (2), and a coil temperature sensor (Sa) is provided in a motor stator. The control device (U1) has a motor output limit means (95) for limiting the current flowing through the electric motor (1) when at least one of the temperature detected by the oil temperature sensor (Sb) and the temperature detected by the coil temperature sensor (Sa) exceeds a corresponding predetermined threshold value. |
