Moreover, since it can be drawn out along the side surface (valley part 34) of the cleaning body holding part 32 by the shape of the protrusion part 40a, it becomes a guide, and the drawing direction (the axial direction of the rotating brush 30) is greater than when there is no protrusion. It can be easily pulled out without shaking and the pulling force can be reduced.
- the second remover 41 can easily remove a lump of dust and the like adhering to the cleaning body 33 without dirtying hands.
- the amount of overlap between the bottom surface of the second remover 41 and the cleaning body 33 is increased in order to increase the scraping force of the second remover 41.
- the attached dust can be scraped off by the protrusion 41a of the second remover 41.
- the bottom surface of the projecting portion 41a is at least dimensioned to contact the cleaning body 33, and the dust removal performance can be improved while the pulling force is small.

このような不具合を解決するものとして、まず、回転ブラシを吸込具から取り外して、回転ブラシの外周に設けたリング状の塵埃除去手段を回転ブラシの軸方向(長手方向)に沿って摺動させると、塵埃除去手段は、ガイドが中空基体の螺旋状の溝に案内されて回転ブラシの軸方向(長手方向)に沿って摺動するので、塵埃除去手段に設けられたカッター刃が溝に接触しながら回転ブラシの軸方向(長手方向)に沿って螺旋状に移動し糸状の塵埃を除去するというものが提案されている(例えば、特許文献1参照)。 A rotary brush is attached to the suction tool of the vacuum cleaner, and this rotary brush rotates and sucks up and sucks dust on the cleaning surface, but if this rotary brush gets tangled with hair, threads, etc. It can no longer function as a rotating brush.
In order to solve such problems, first, the rotating brush is removed from the suction tool, and the ring-shaped dust removing means provided on the outer periphery of the rotating brush is slid along the axial direction (longitudinal direction) of the rotating brush. In the dust removing means, since the guide is guided in the spiral groove of the hollow base and slides along the axial direction (longitudinal direction) of the rotating brush, the cutter blade provided in the dust removing means contacts the groove. On the other hand, there has been proposed one that moves spirally along the axial direction (longitudinal direction) of the rotating brush to remove thread-like dust (see, for example, Patent Document 1).
