(54) Vacuum cleaner


(57) The vacuum cleaner includes a vacuum cleaner body (20) having a dust collector (60) and an electric blower (33) for producing an intake negative pressure in the dust collector, a filter (100) for separating dust absorbed in the dust collector with air by the negative pressure, and a dust dumping member (304) for dumping the dust attached to the filter by vibrating the filter. Moreover, the vacuum cleaner includes a handle (200) mounted on the vacuum cleaner body for carrying the vacuum cleaner body, the handle being movable in a vertical direction between a storing position and a using position; a storage spring (323) for energizing the handle to the storing position; and a power transmission unit (300A) for driving the dust dumping member by linking with the vertical movement of the handle.
