PROBLEM TO BE SOLVED: To provide a semi-dry sump engine in which the longitudinal dimension thereof can be made compact and an oil capacity can be increased without lowering output by stirring oil. SOLUTION: In this engine, a crankcase is vertically divided into two parts and the lower part of a transmission case in the crankcase is formed as an oil reserving part. A crankshaft 7 and an output shaft 15 are disposed so that these axes O1, O2 are positioned at the upper and lower mating faces S of the crankcase 1. The input shaft 14 is disposed on the upper side of the mating face S. As viewed in the axial direction, the input shaft 14 is disposed so that an angleθ1 formed by a line segment O1-O2 connecting the axis O2 of the input shaft 14 to the axis of the crankshaft 7 and a cylinder centerline C on the upper side of the axis O1 of the crankshaft 7 is an acute angle.
