The present invention discloses an automatic balancing apparatus including moveable balancing members located in hollow tubular portions of a rotating member which may include a rotation shaft and a turntable. The automatic balancing apparatus suppresses vibration of the rotation shaft and turntable by adjusting a center of gravity with balancing members so that even high speed rotation of the shaft is possible without excessive vibration. The present invention uses magnets and may use low friction surfaces to further improve the free and fine movement of the balancing members which ensures a finely tuned balancing apparatus in operation.
