A spring 17 is attached between the body housing part 8 and the end face thereof. Next, the other main body member 3 is joined to this main body member 3 with the dividing surfaces 2 of both parts abutting each other. Next, by fitting and fixing a pair of cap bodies 21 to both ends of the joined main body members 3, that is, the rotary brush main body 1, the both main body members 3 are held in a joined state. Then, through the insertion holes 24 of both cap bodies 21,
A pair of shafts 26 are inserted and fixed into each bearing portion 10 of the rotating brush body 1, respectively.
また、上述と逆の手順により、回転ブラシを分
解することができる。 Further, the rotating brush can be disassembled by the reverse procedure to the above.
次に、この実施例の作用について説明する。 Next, the operation of this embodiment will be explained.

That is, with this rotating brush facing the suction port, both shafts 2 are attached to the bearings provided inside the suction port body.
6 is pivotally supported, and a belt is passed between a pulley fixed to the rotating shaft of the electric motor and the pulley portion 25 of the rotating brush, so that the rotation of the electric motor etc. is transmitted to this rotating brush.

掃除面から塵埃を掻き出す。 During cleaning, as the rotary brush main body 1 rotates, the beater section 6 provided on its outer circumferential surface presses against the surface to be cleaned, such as a carpet, while the brush also provided on the outer circumferential surface presses against the surface to be cleaned, such as a carpet. The bristles 4 scrape out dust from the surface to be cleaned.

付けたりすることはない。 When the rotating brush body 1 is rotating in this way, as shown in FIG.
Inside, the weight body 12 of the sliding body 11 is connected to the rotation axis a.
This weight body 1 is deviated from
2 moves in a direction away from the rotation axis a against the biasing force of the spring 17 due to the centrifugal force accompanying the rotation. Then, the cutter 13 attached to the weight body 12 also moves, and the cutter 13 is completely recessed into the rotating brush body 1. Therefore, the plate-shaped cutter 13 does not get in the way during cleaning, and the cutting edge 16 does not damage the carpet or the like.
また、前述のように、回転ブラシ本体１内にお

ようなことはない。 Further, as described above, in the rotating brush body 1, two sliding bodies 11 are arranged side by side in the direction of the rotation axis a, and each sliding body 11 protrudes in a symmetrical direction with respect to the rotation axis a. The weight distribution within the brush body 1, especially the position of the weight body 12 which has a considerable weight, becomes more symmetrical about the rotation axis a, so the balance during rotation is good and the rotational force of the rotating brush body 1 is impaired. There's no way you'll be disappointed.
一方、回転ブラシ本体１が停止しているときに

行なえ、手間を要することなく糸くずなどを除去
することができる。 On the other hand, when the rotating brush main body 1 is stopped, as shown in FIG. protrudes a predetermined amount from In this state, lint or hair wrapped around the outer circumferential surface of the rotating brush body 1 during cleaning is pressed by the cutter 13 and separated from the outer circumferential surface, and in some cases, the cutter body 13 is cut by the sharp cutting edge 16 of.
If lint or the like is cut off, the lint or the like can be removed by simply wiping the outer circumferential surface of the rotating brush body 1 lightly without touching it directly with your hands, that is, without getting your hands dirty. In addition, even if the lint is not cut, the lint and the like are separated outward from the outer circumferential surface of the rotating brush body 1, making it easier to pick up the lint and the like directly, compared to the case where grooves are provided on the circumferential surface of the rotating brush body 1. Alternatively, operations such as cutting the lint by inserting scissors or the like between the lint and the outer peripheral surface can be performed more easily, and the lint can be removed without any effort.
また、このように回転ブラシ本体１を常に清浄
な状態に保つことができるので、その回転力の低
下も防止される。 Furthermore, since the rotating brush main body 1 can be kept in a clean state at all times in this way, a decrease in its rotational force is also prevented.
なお、回転ブラシ本体１に巻着いた糸くずなど

易に除去できる。 In addition, since the lint and the like wrapped around the rotating brush body 1 hangs on the beater part 6, the sliding body 11 is moved outward from the common tangent between the outer surface of the beater part 6 and the outer circumferential surface of the rotating brush body 1. It is necessary to stand out. Of course, in order to remove lint etc. more easily, the amount of protrusion of the sliding body 11 should be larger.
It will be more effective if it stands out. In addition, if lint or the like gets caught on the beater part 6 and the brush bristle part 4, the lint or the like will be closest to the outer circumferential surface of the rotating brush body 1 at an intermediate position in the rotation direction b between the two. As in the example, the sliding body 11 is located at an intermediate position between the beater part 6 and the brush bristle part 4.
If it is made to protrude, lint etc. can be removed more easily.

ない。(Effects of the Invention) According to the present invention, the sliding body provided in the rotating brush main body so as to be slidable in the centrifugal direction thereof is entirely immersed in the rotating brush main body by the centrifugal force caused by the weight body during rotation. In addition, when the brush is not rotating, the tip of the cutter protrudes outward from the outer circumferential surface of the rotating brush body, so lint, hair, etc. that have wrapped around the outer circumferential surface of the rotating brush body as it rotates during cleaning will be removed after cleaning. Since the sliding body separates the lint from the outer circumferential surface of the rotating brush body, these lint can be easily removed, and the rotating brush body can always be kept clean, so that its rotational force can be reduced. Further, since there is no need to provide a large groove opening outward in the rotary brush body as in the conventional case, there is no decrease in the strength of the rotary brush body.
