Abstract
A large gear and a small gear are provided to an intermediate shaft of an in-wheel motor drive device, and a final output gear configured to mesh with the small gear of the intermediate shaft is provided to an output shaft. The output shaft is supported by bearings on in-board and out-board sides, respectively, and the large gear of the intermediate shaft is arranged between the bearing configured to support the output shaft on the in-board side and the final output gear of the output shaft. The bearing and the large gear are arranged so that, when viewed from the axial direction, a tooth top circle of the large gear of the intermediate shaft and a radially outer circle of the bearing configured to support the output shaft on the in-board side have an intersection point.
