Claims

[Claims for Utility Model Registration] Consisting of a transmission that changes the engine output, and a final reduction gear that decelerates the output of the transmission and transmits it to the left and right wheels, the output of the transmission is transmitted to the final reduction gear. A transmission shaft for transmitting data is arranged to extend in the front and rear of the vehicle, and the final reduction gear is connected to the transmission shaft and has a drive pinion having a rotating shaft extending in the front and back of the vehicle, and meshes with the drive pinion so as to rotate in the vehicle width direction. For automobiles, it is comprised of an orthogonal conversion gear set consisting of a ring gear that rotates around an axis extending from the center, and a differential gear set that is attached to the ring gear and distributes and transmits the power transmitted to the ring gear to the left and right wheels. In the drive device, an outer circumferential surface of a differential gear case that holds the differential gear set faces one end surface of the drive pinion, and one end is opened in the one end surface and the outer circumferential surface of the differential gear case holding the differential gear set is open in the axial direction along the shaft center. an extended first lubrication hole;
An automobile drive device characterized in that a second lubrication hole extending radially outward from the first lubrication hole and opening at a connection portion with the transmission shaft is provided in the drive pinion.
