PROBLEM TO BE SOLVED: To reduce the vibration and speed fluctuation of a belt wound around a rotating body, by reducing a vibration component which is a contributing factor of rotating speed fluctuation and obtaining the stable rotation of the rotating body. SOLUTION: A belt rotation drive device comprises: a rotating body system 60 supporting the rotating body 4 around which a belt 1 is wound; a drive system 61 having a rotation drive source 5 rotating and driving the rotating body system; a drive transmission 62 for coupling the rotating body system and the drive system. In this belt rotation drive device, a centrifugal pendulum damping means 9 is provided to at least the rotating body system 61. |
