る。According to the invention of claim 6 of the present invention, the electric blower for sucking dust and the dust collecting chamber on the suction side thereof are provided.
The filter according to any one of claims 1 to 5, wherein a flow having a high flow velocity in a suction side or an exhaust side passage of the electric blower passes through a dense part, and a flow having a low flow velocity passes through a sparse part. Since the air flow velocity after passing through the filter becomes uniform, turbulence can be prevented and noise can be reduced, and the smooth air flow is not hindered. Therefore, a vacuum cleaner having a strong suction force can be provided.
