ABSTRACT:
A balancing apparatus which is capable of compensating for an eccentricity generated even when a rotating member is rotated at a velocity that is lower than a critical velocity thereof. Preferably, the balancing apparatus is disposed, in relation with the rotating member, at a position spaced apart from a rotation center of the rotating member by a predetermined distance. The balancing apparatus includes a plurality of balls for compensating for an eccentricity, a hardening agent for fixing the balls under the condition that the eccentricity is compensated by the balls, and a keeping member for insertion of the balls and the hardening agent.
