摘要： A motor driving force transmission device includes electric motors which produce motor driving force with which a rear differential is operated and a speed reduction and transmission mechanism which reduces the speed of the motor driving force of the electric motors and transmits it to the rear differential. The speed reduction and transmission mechanism has eccentric cams which rotate as the electric motors are driven, transmission members which rotate as the eccentric cams rotate, and is disposed on an outer circumference of the rear differential.

摘要： A speed reduction mechanism includes: a speed reduction unit that includes an input member formed of an external gear that makes circular motion about a rotation axis with an eccentric amount, and a rotation force applying member formed of an internal gear that is in mesh with the input member; and a lubricating oil supply unit that supplies lubricating oil to a bearing of the speed reduction unit. The lubricating oil supply unit includes an oil tank arranged outside of the rotation force applying member, an oil delivery passage that delivers the lubricating oil to the oil tank, and a first oil introduction passage that introduces the lubricating oil from the oil tank to the bearing. The lubricating oil is delivered to the oil delivery passage through pumping action of the input member based on the circular motion.

摘要： A cage of each of ball bearings arranged on respective outer peripheries of eccentric portions of a motor shaft has an annular base portion interposed between an inner ring and an outer ring and a plurality of partition wall portions for forming pockets together with the base portion. In a first ball bearing, part of the base portion protrudes axially outward from the inner raceway and forms an oil receiving portion that receives lubricating oil from the second rolling bearing side, at a portion around the rotation axis and axially outward of the first rolling bearing.
