The impeller is rotated in response to an air flow produced by a suction force and a brush or a blade member is mounted in a spiral shape along the whole impeller or a part of the impeller and contacts a surface to be subjected to cleaning. The rotary brush rotates integrally with the impeller on the same shaft and no partition wall is provided between the impeller and the rotary brush. A suction nozzle body having a small size, and which is of light weight and provides for silent operation, and a vacuum cleaner using the same, can be provided.
