SUCTION TOOL FOR ELECTRIC VACUUM CLEANER AND ELECTRIC VACUUM CLEANER USING THE SAME

摘要

PROBLEM TO BE SOLVED: To prevent the vibration and noise of a rotary brush due to the shake and twist of the rotary brush itself of a suction tool main body and to surely hold a rotary cleaning body. SOLUTION: The rotary brush 30 incorporated in the suction tool main body is composed of highly accurate rotating bodies 35 divided into two or more pieces and the rotating bodies 35 are provided with a plurality of grooves 35 to insert and hold a bristle brush 37 and a peripheral blade 38. The groove 36 is tapered in a longitudinal direction and a narrow width part and a wide part are provided for each rotating body 35. Then, the bristle brush 37 and the peripheral blade 38 are inserted and held in the grooves 36, holding force is increased at the narrow dimension part of a tapered part, a plurality of the parts are uniformly provided on a plurality of the rotating bodies 35 and the bristle brush 37 and the peripheral blade 38 are surely held during cleaning work. Thus, the rotary brush with excellent durability and with less vibration sound and noise is attained.
