PROBLEM TO BE SOLVED: To prevent long dust such as hair, fallen hair of pets, or lint from being entangled in a rotary brush in a suction tool 10 for a vacuum cleaner which has the rotary brush 20.SOLUTION: The rotary brush 20 includes a wing cloth 25. The wing cloth 25 makes contact with a cleaned surface 400 and is curved backward in the rotating direction of a rotary shaft 21 while facing a suction opening 16, and stretches up to rise from the peripheral surface of the rotary shaft 21 when moving inward into a storage chamber 15 away from the cleaned surface 400. When the wing cloth 25 stretches up, sticking long dust H is flown in a direction away from the peripheral surface of the rotary shaft 21. Before the long dust H is entangled in the rotary brush 20, the long dust H is flown outward by the wing cloth 25 and prevented from being entangled in the rotary brush. |
