ABSTRACT:
A vacuum cleaner comprises a floor nozzle housing an agitator for stirring dust, a handle sector containing a dust bag and a fan motor for sucking dust, and a power transmission device for transmitting the driving force of the fan motor to the agitator. The handle sector is tiltably attached to the floor nozzle at a rear section. The power transmission device comprises a driving pulley fixed to the agitator, an idling pulley attached adjacent to the driving pulley and rotating free from the agitator, and a belt provided between the fan motor and one of the driving pulley and the idling pulley. A switching lever is provided for switching the position of the belt to the driving pulley or to the idling pulley, which motion is coupled with the tilting motion of the handle sector. The driving force of the fan motor is conveyed to the agitator in accordance with the tilting motion of the handle sector.
