The rotor of a driving device comprises an output shaft with transmission wheels fixed on the output shaft. The rotor is provided with a plurality of rotor bodies and a transmission device which is interlocked with the transmission wheels. Each rotor body is equipped with a plurality of 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 positions 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. In addition, the balance bodies also rotate in association with the rotation of these rotating bodies. Therefore, 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.
A driving device comprising an output shaft having a first transmission gear, a plurality of rotor bodies each having a second transmission gear engaged with said first transmission gear, each of said rotor bodies comprising a support shaft, each of said rotor bodies further comprising a plurality of axially spaced rotating body parts rotatably mounted on said support shaft, balance pieces each having an eccentrically located pin, said pin being rotatably mounted on an outer peripheral portion of said rotating body parts such that said balance pieces are rotatable relative to said rotating body parts, crank means rotatably mounted on said support shaft between two axially spaced rotating body parts, said crank means comprising a crank body and two diametrically opposed crank plates pivotably mounted on said crank body, said crank plates having elongated holes, a first connecting pin connected to a rotating body part disposed on one axial side of said crank means and extending into the elongated hole of one crank plate, and a second crank pin connected to a rotating body part located on the other axial side of said crank means and extending into the elongated hole of the other diametrically opposed crank plate.
