An in-wheel motor drive assembly includes a motor case defining a motor chamber and a reduction mechanism chamber provided on one side of and isolated from the motor chamber by a partition wall. An electric motor is mounted in the motor chamber. A planetary gear reduction mechanism is mounted in the reduction mechanism chamber, and reduces the rotation of the electric motor and outputs the reduced rotation to a hub ring. The reduction mechanism is lubricated by lubricating oil stored in the reduction mechanism chamber. A tapered oil guide surface is formed at the center of the inner surface of the partition wall facing the reduction mechanism chamber. The oil guide surface guides lubricating oil splashed up by the rotating reduction mechanism and flowing down along the inner surface of the partition wall, onto the rotor shaft of the electric motor, thereby lubricating bearings mounted on the rotor shaft.
