A combustion engine (E) for a motorcycle includes a supercharger (42) which pressurizes intake air (I). The supercharger (42) is driven by power of the combustion engine (E). A first cushioning body (69) which suppresses rotation fluctuation of power is provided on a power transmission path (P) leading from the combustion engine (E) to the supercharger (42). The first cushioning body (69) has a damper structure to transmit power from an upstream side to a downstream side thereof through an elastic body (128).
