The present invention relates to an apparatus of driving an agitator of an upright vacuum cleaner. It includes a fixing panel and a rotation guide which are positioned at an outer side of the driving shaft roller and guided to move coaxially with the driving shaft roller so as to conveniently switch a power transmitted to an agitator by a user's foot; a support sphere and a roller support part which are formed in a direction of an axis parallel with the driving shaft roller on an outer circumference of the rotation guide; an idle roller which is inserted into the roller support part; a manipulating means connected with the support sphere, for controlling the rotation guide so that the elastic member is selectively wound around the driving shaft roller or the idle roller; and a stop means for maintaining a position of the rotational driving part stably.
