Claim:
1. A power unit for a vehicle, comprising: a transmission adapted to transmit rotational power from a crankshaft, rotatably supported on a crankcase, to a drive axle with speed change, the transmission accommodated in the crankcase and comprising a first main shaft and a second main shaft which are rotatably and coaxially supported on the crankcase, first and second hydraulic clutches disposed coaxially with the first and second main shafts, the first and second hydraulic clutches configured to be selectively engaged and disengaged to effect and interrupt transmission of power between the crankshaft and the first and second main shafts, a clutch cover covering the first and second hydraulic clutches, the clutch cover connected to the crankcase, and a clutch actuator adapted to control switching of engaging and disengaging operations of the first and second hydraulic clutches, the clutch actuator mounted to the clutch cover, wherein a first set of valves, out of a plurality of valves constituting part of the clutch actuator, are disposed in a first actuator body mounted to an outer surface of the clutch cover and disposed at a position such that at least part of the first actuator body overlaps with the first and second hydraulic clutches when viewed from a direction along an axis of the first and second main shafts, with axes of operation of said first set of valves set along a plane intersecting the axis of the first and second main shafts, and wherein a second set of valves of said plurality of valves are disposed in a second actuator body mounted to the clutch cover so as to overlap with the first actuator body at an opposite side from the clutch cover.
