PROBLEM TO BE SOLVED: To provide a differential gear capable of surely preventing seizure of a sliding part in the differential gear even when the differential gear is arranged between a reduction gear and a drive motor in which a differential gear is a driving source and actuated in accordance with direct output from a drive motor. SOLUTION: The differential gear is provided with a differential case 14 disposed between a reduction mechanism 30 for reducing output of a drive motor 11 and the drive motor 11, a pinion shaft 36 included in the differential case 14 so as to be orthogonal to a rotating direction of the differential case 14, a pinion gear 37 equipped so as to be coaxial to the pinion shaft 36 in the differential case 14 and a pair of side gears 34, 35 meshed with the pinion gear 37. A lubricating type bearing 38 is interposed in a sliding part 36c of the pinion shaft 36 rotating with respect to the pinion gear 37 or the differential case 14. COPYRIGHT: (C)2006,JPO&NCIPI
