Abstract
A vehicle power transmission device includes: a differential mechanism and provided with a through-hole in an outer circumferential surface, a pair of pinion gears respectively fitted to both ends of a pinion shaft, and a pair of side gears rotatably supported by the differential case and meshed with the pinion gears; and a baffle plate that includes an oil passage component functioning as an oil passage for supplying a lubricating oil for lubricating the pinion gears and the side gears and that is fixedly disposed to cover an outer circumference of the differential case. The oil passage component is provided with an opening portion allowing the lubricating oil in the oil passage to flow out downward, and the opening portion is disposed above the pinion shaft and between a pair of inner-circumferential-side end surfaces of the pair of the pinion gears when the pinion shaft is horizontal.
