ABSTRACT:
A dust cover sealing apparatus of a vacuum cleaner comprises a first fence protruding from an edge of a dust collecting chamber and having a predetermine height, and a second fence protruding from an inner surface of the dust cover to contact an end of the first fence when the dust cover is mounted on a cleaner body, and a plurality of guide ribs protruding from an inner surface of the dust cover adjacent to a side of the second fence, for guiding the second fence so that ends of the first and second fences contact each other when the dust, cover is mounted on the cleaner body. Accordingly, the sealing efficiency of the dust collecting chamber is maintained, and the manufacturing cost is reduced.
