Patent ID: 7107647

Claim:
An apparatus for driving an agitator of an upright vacuum cleaner, the apparatus comprising: a motor for driving a suction fan of the vacuum cleaner; a driving shaft roller installed at an end of the motor, around which a power transmission member is wound intermittently; a bushing mounted on an outer circumference of the driving shaft roller; a fixing panel fixed to the vacuum cleaner; a rotational driving part which the bushing is inserted at a center thereof, the rotational driving part rotating around the driving shaft roller; a selection lever rotating around a lever hole hinge-coupled to the fixing panel by an applied external force; a selection link one end of which is hinge-coupled to the body of the selection lever; a link connecting part extending in a direction of an axis parallel with the driving shaft roller on an outer circumference of the rotational driving part and coupled with the other end of the selection link; a roller support part extending in an opposite direction from an extension of the link connecting part; an idle roller on an outer circumference of the roller support part and around which the power transmission member is wound intermittently due to rotation of the entire rotational driving part so that power is controlled to be transmitted; and a stop means for maintaining a position determined by a self-rotation of the rotational driving part.
