SUCTION TOOL OF VACUUM CLEANER

摘要

PROBLEM TO BE SOLVED: To improve removal performance not only for relatively large dust but also for fine dust, to eliminate re-sticking of removed dust onto a floor surface and to reduce a manufacturing cost. SOLUTION: A rotary cleaning body 4 provided so as to be rotated only in a single direction facing a suction port 3 of a suction tool body 1 is formed of a rotary shaft 41 and a cleaning body 42 extended and disposed in an axial direction on the outer periphery of the rotary shaft 41. Also, the cleaning body 42 is constituted of two layers of brush strings, and the brush string 422 positioned on the rotating direction front side is set such that the flexural modulus of the brush fibers is weaker than the flexural modulus of the brush fibers of the brush string 423 positioned on a rotating direction rear side.
