Abstract:
A rotary-body driving-force transmitting mechanism transmits a driving force from a driving-force source to a rotary body. A rotary-inertial-body driving-force transmitting mechanism transmits the driving force to a rotary inertial body that suppresses a velocity fluctuation in the rotary body. A rotational velocity shift mechanism shifts the rotational velocity. The rotary inertial body, the rotary-body driving-force transmitting mechanism, and the rotary-inertial-body driving-force transmitting mechanism are provided coaxially with a rotary shaft of the rotary body. A satellite frictional gear mechanism is used as the rotational velocity shift mechanism.
