• The powertrain mechanism has adopted the same spray oiling system, and an oil pipe in addition to a funnel and oil path have been adopted.
• The oil path uniformly distributes raised transaxle oil and supplies it to each part.
• The oil pipe intakes the transaxle oil flowing through the oil path via the funnel. While the intake transaxle oil flows rearward in the primary shaft by the spiral-shaped groove in the oil pipe, the oil is uniformly distributed and supplied to each part by the centrifugal force occurring with the primary shaft rotation.
• The powertrain mechanism can operate with a lesser amount of transaxle oil due to the oil path and oil pipe, and flowing resistance from the powertrain mechanism transaxle oil is reduced.
