Engine power generator and vehicle

The invention relates to an engine power generator comprising a stator, a rotor and a power transmitting means for transmitting an engine power to the rotor and, further, to a vehicle, in particular a motorcycle, comprising an engine and a propulsion unit. The invention aims to form an engine power generator into a small and light configuration while preventing the function thereof from being impaired. Therefore, the invention proposes that the rotor and/ or at least a member of the power transmitting means are rotatably supported relative to a revolving shaft penetrating a center axis thereof and, further, that a vehicle comprises such an engine power generator.
