Abstract
A vehicle power transmission device mounted on a vehicle for transmitting power from a power generating source to an axle through a gear train accommodated in a case, including: a lubricating pump that is accommodated in the case and which is driven by the power generating source and is capable of supplying a lubricating medium to an element to be lubricated; a lubricating medium storage portion that stores the lubricating medium; a lowermost gear that is located at a lowest position in the case, and which scoops up the lubricating medium in an inner bottom of the case toward a center of the case during normal rotation of the axle without guiding the lubricating medium along an inner wall surface of the case; a partition wall; and a lubrication flow path that guides the lubricating medium scooped up by the lowermost gear to a predetermined element to be lubricated.
