<P>PROBLEM TO BE SOLVED: To maintain stable suction power with a nozzle as a whole even if a floor nozzle for use in a vacuum cleaner is lifted off a floor due to obstacles or the like. <P>SOLUTION: The suction port of the floor nozzle for use in the vacuum cleaner is formed into V-shape having a front side provided with a triangular protrusion, and further the apex of the protrusion is positioned higher relative to the bottom of the suction port so that the suction power can be divided in three. Accordingly, the floor nozzle can be normally used without losing the suction power nearly at both ends of the nozzle even if the nozzle is lifted up due to the obstacles during use. <P>COPYRIGHT: (C)2013,JPO&INPIT |
