ABSTRACT:
An improved lubrication structure is provided in an engine by optimizing the structure for recovering scooped oil for enhanced oil recovery efficiency. The oil, which has been scooped up and scattered by the rotation of a clutch, is captured within a concave groove provided within a cylindrical inner surface of a case cover facing the clutch. The captured oil is smoothly guided from the concave groove to an oil receiver of a crankcase via a bent upper edge part of an oil guide plate. The recovered oil passes through dropping holes of a recovered oil path and is supplied to a gear engagement part of a transmission system located below the recovered oil path.
