Abstract

Provided is an in wheel motor drive device configured so that a speed reduction mechanism and a bearing for supporting a rotor shaft can be reliably lubricated with oil. A motor housing chamber (17) is provided within a motor case (10) and a speed reduction section housing chamber (18) is provided on one side of the motor housing chamber (17) so as to be separated therefrom. An electric motor (30) is mounted in the motor housing chamber (17). A planetary gear speed reduction mechanism (40) is mounted in the speed reduction section housing chamber (18) the planetary gear speed reduction mechanism (40) reducing the speed of the electric motor (30) and outputting the reduced speed to a hub ring (65). The speed reduction mechanism (40) is lubricated by lubricating oil contained within the speed reduction section housing chamber (18). A tapered oil guide surface (21) is provided at an inner surface center section of the partition wall (16) between the motor housing chamber (17) and the speed reduction section housing chamber (18) the inner surface center section facing the speed reduction section housing chamber (18). The lubricating oil carried up by the rotation of a planetary gear (44) and flowing down along the inner surface of the partition wall is conducted from the oil guide surface (21) onto the rotor shaft (34) of the electric motor (30) and a bearing (47) provided on the rotor shaft (34) is lubricated with the oil.
