Abstract
An in-wheel motor drive device is attached to an inner side of a wheel of a vehicle wheel and drives the vehicle wheel. The in-wheel motor drive device includes a rotating electric machine; a transmission mechanism that transmits the rotation of the rotating electric machine; a speed reducing mechanism that reduces in speed the rotation transmitted by the transmission mechanism; and an output shaft that outputs the reduced-speed rotation of the speed reducing mechanism to the wheel. The speed reducing mechanism and the output shaft are disposed on a first axis coaxial with a center of the wheel. The rotating electric machine is disposed on a second axis parallel to the first axis, and the rotating electric machine and the speed reducing mechanism are positioned in a radial cross section perpendicular to the first axis and the second axis.
