The rotor of a driving device comprises an output shaft with transmission wheels fixed on the output shaft. The rotor is provided with rotor bodies and a transmission device which is interlocked with the transmission wheels. Each rotor body is equipped with rotating body parts on a support shaft in a free rotatable manner. Balance bodies are attached to these rotating body parts through pins located at eccentric position of these balance bodies in a manner to provide free rotation. Crank bodies, driven by the rotating bodies, are freely-rotatably equipped on the support shafts. Where the output shaft rotates by an input from an external source, the rotating bodies also rotate at the same time. The balance bodies also rotate in association with the rotation of these rotating bodies. The crank bodies prevent a state that parts of the balance bodies protrude outwardly from the rotating bodies. Thus, the inertial force of the rotating bodies is ensured. |
