Abstract:
Object In a power unit for a motorcycle that includes an internal combustion engine provided with a crankcase rotatably supporting a crankshaft with an axial line extending in a vehicle-width direction, and a power transmission device for changing and reducing the speed of rotational power from the crankshaft and transmitting the resulting rotational power to a rear wheel, an oil pump being mounted on the crankcase, a balancer being rotatably supported by the crankcase, rotational power from the crankshaft being transmitted to a pump driven member provided on a pump shaft of the oil pump and to a balancer driven member coaxially interlinked with and connected to the balancer so as to transmit power to the balancer, the power unit is downsized by bringing a balancer and an oil pump into close arrangement. Solving Means The pump driven member 236 and the balancer driven member 249 are offset from each other in a vehicle-width direction and are located at such a position as to at least partially overlap each other as viewed from the side of the vehicle-width direction.
