Abstract

A plurality of circumferential finsare formed on an outer peripheral surface of a motor casing, and a plurality of finsare formed on an outer surface of a motor rear cover. Lubricant circulates in a motor-casing oil passageprovided in the motor casing, a motor-rear-cover oil passageprovided in the motor rear cover, and a speed reduction portion B. This lubricant is cooled when flowing in the motor-casing oil passageand the motor-rear-cover oil passage. Thus, an in-wheel motor drive deviceis efficiently cooled.
