Kind Code:
A1
Abstract:
An in-wheel motor drive device (11) is provided with: a motor unit which rotationally drives a motor-side rotary member; a deceleration unit which decelerates the rotation of the motor-side rotary member and transmits the decelerated rotation to a wheel-side rotary member; a wheel hub (26) which is fixedly coupled to the wheel-side rotary member; a wheel hub bearing which rotatably supports the wheel hub (26); a casing (12) which covers the motor unit, the deceleration unit, or the wheel hub bearing; a plurality of sensors (43) which are mounted to the casing (12) and capable of detecting distortion occurring in the casing (12); and a signal processing unit (46) which calculates a load applied to a wheel on the basis of distortion signals outputted by the sensors (43).
