Zusammenfassung:	An improved lubrication structure is provided in a 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.
