Since the height of the floor suction tool for the vacuum cleaner is almost determined by the maximum rotation diameter L1 of the brush portion 4a of the cleaning body 4 provided in the rotary rotor 1, the height of the floor suction tool for the vacuum cleaner is lowered. It is necessary to make the rotation diameter L1 of the rotary rotor 1 as small as possible. However, in the configuration of the conventional rotary rotor 1 described above, the distance G between the bottom surface of the one groove 2 and the bottom surface of the other groove 2 is set to a predetermined size, that is, predetermined from the viewpoint of ensuring the required strength of the rotor 3. The wall thickness of the rotary rotor 1 must be reduced.

  In order to reduce the rotation diameter L1 of the rotary rotor 1, a method of shortening the brush portion 4a of the cleaning body 4 is also conceivable. However, when the brush portion 4a is formed of, for example, an extremely fine fiber, the fiber strain is reduced. It becomes stronger, and the performance of scratching the surface to be cleaned or scraping dust on the surface to be cleaned is reduced. Further, when the brush part 4a is formed of a blade made of vinyl chloride or the like, there is a problem that the bending performance is deteriorated and consumed at an early stage.

A cleaning body 32 that scoops up dust on the surface, a bearing holder 33 with a pulley that is press-fitted into one end of the rotor 30 and over which one end of the belt 23 is stretched, and a bearing holder 34 that is press-fitted into the other end of the rotor 30 Has been. Reference numeral 35 denotes a bearing that rotatably supports each of the bearing holder with pulley 33 and the bearing holder 34 and is held by the inner wall 36 of the suction tool 10.

  As shown in FIG. 3, the cleaning body 32 fixes a brush portion 32 a made of a large number of ultrafine fibers and the like, and a base portion 32 b that is detachably mounted in a groove 31 provided in the rotor 30 while fixing the lower end of the brush portion 32 a. It is composed of The brush portion 32a is not limited to fibers, but may be formed of a blade-like material made of a soft material such as vinyl chloride, or a non-woven fabric. The method of fixing the brush portion 32a and the base portion 32b is not particularly limited, for example, the brush portion 32a is implanted in the base portion 32b, the two are bonded, or one is sandwiched between the other.

In the present embodiment, when the base portion 32b is attached to the groove 31 while the brush portion 32a protrudes from the opening 31a of the groove 31, the root portion 32c of the brush portion 32a rotates the rotor 30 as shown in FIG.
