Dust collecting unit for use in cleaner

A vacuum cleaner of the present invention guides air and dust sucked from an inletto a dust collection chamberthrough a guide path. A cylindrical passage memberis located at a linear section of the guide pipeso that its axial line may come along a direction in which the linear sectionextends. A plurality of vent holesare formed on the passage memberand each of the vent holesis covered with a mesh filter. When dust is accumulated in the dust collection chamberto some extent, air flowing into a lead-in pipeflows to the outside (the side of a bypass passage) through the vent holesand is guided directly to an outlet by bypassing the dust collection chamber
