Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a power unit (1) capable of reducing friction inside a mechanical reduction gear (19) and increasing the flexibility of disposition of gear shafts (63) and (14) of a mechanical reduction gear (19), wherein the power unit (1) includes a drive wheel (15) rotatably supported in the rear of a V-belt automatic gear (18) and the mechanical reduction gear (19) provided between the rear of the V-belt automatic gear (18) and the drive wheel (15) and decelerating rotations of a driven shaft (52) of the V-belt automatic gear (18) to transmit it to the drive wheel (15).SOLUTION: The power unit (1) includes a lubrication oil pump (67) provided on the lowermost part inside a gear case (60) housing the mechanical reduction gear (19) and for supplying oil housed inside to meshing part (82) of gears of the mechanical reduction gear (19). The oil pump (67) is housed in an oil pump disposition space (70) formed by a manner that bottom walls of gear case members (50R) and (60R) constituting the gear case (60) extend downward.
