PURPOSE:To enhance the assembly accuracy of an entire engine by tilting the longitudinally mounted engine to one lateral side, specifying the forming position of a mating surfaces of the engine and an oil pan located thereunder, and forming a differential case on the titled surface on the tilted side of a cylinder block. CONSTITUTION:In an arrangement of a power plant P mounted longitudinally on a vehicle V with the power plant as a unit comprising an engine 1, a clutch 2, a transmission 3, and a differential device D, the engine 1 is disposed with the cylinder axis line L1 tilted to one lateral side with respect to the vertical line. While an oil pan 13 is mated to the bottom surface of the cylinder block 6, the mating surface P1 is perpendicular to the axial line L1 and located parallel to and lower than a crank center surface P2. A differential case body 171 is formed on the side surface on the titled side of the cylinder block 6 so that an intermediate transmission shaft 12 spanning from the cylinder block 6 to the oil pan 13 and link motion connecting the differential device D to a driven wheel is passed through an supported with the differential case body.
