The present invention relates to a vacuum cleaner, and there is provided a nonpowered vacuum cleaner comprising: a housing having a moving handle at one side of an upper surface, an open/close hole on a bottom surface, and an inhalation hole provided at a bottom of a front portion thereof; an exhaust hole provided on the other side of the upper surface of the housing; rolling wheels coupled with both sides of the housing, respectively; a gear portion which is mounted inside the housing and provided to convert and deliver a rotational force of a shaft of the rolling wheel; an inhalation fan which is provided to take air in from the inhalation hole and rotates by the rotational force delivered from the gear portion; a cleaning roller which is coupled with a rear end of the bottom of the housing and removed therefrom, wherein an outer circumferential surface of the cleaning roller is made of an adhesive collecting surface. Since the nonpowered vacuum cleaner according to the present invention can be operated by human power without requiring an external power source, the vacuum cleaner can be used in a place where electricity is not available. And, a size of the vacuum cleaner can be reduced such that the vacuum cleaner can be utilized on a table, since a gear structure for rotating an inner fan is simple. Also, a constant dust suction power can be maintained by incorporating a freewheel structure. Furthermore, since a cleaning roller having an adhesive outer circumferential surface is provided on the bottom of the cleaner and the cleaning roller is operated to protrude to outside only when an operation lever is held for a cleaning job, it is possible to perform cleaning efficiently and maintain a constant viscosity. |
