PROBLEM TO BE SOLVED: To provide a simple means for performing the synchronizing driving of a rotor, to reduce the number of the constitutional parts of the rotor itself for power transmission and deceleration and to ensure the safety of operation while preventing the change of the characteristics of capacity. SOLUTION: A pair of rotors 5 fitted with screw threads having mutually converged axial lines and a means 7 synchronously transmitting power across the rotors 5 are provided and the respective rotors 5 are rotated by motors 8. |
