The protruding piece 1 is inserted from the large diameter part 12 side of the shaft bearing part 4 of the mounting part 2.
When fitted with 8 and 18 at the beginning, the projecting pieces 18 and
The protruding portions 19 of 18 are elastically deformed so as to contact the tapered portion 14 and approach each other on their free end sides,
It is press-fitted into the small diameter portion 13. Then, as shown in FIG. 4, when the protrusions 19, 19 pass through the small diameter part 13 and come out, the elasticity of the protrusions 18 causes the protrusions 19, 19 of the protrusions 18, 18 to The upright wall 19a at the rear end of the protruding portion 19 contacts the tip of the shaft bearing portion 4 on the outside of the small diameter portion 13, and the projecting pieces 18, 18 are in the small diameter portion 13 of the shaft bearing portion 4. Further, since the shaft 17 remains located in the large diameter portion 12 and cannot be moved, the grip 3 does not come off from the mounting portion 2 and is rotatably supported.

態で形成されている。 Further, the adhesive sheet 22 of the dust removal roller 20 is partially cut by inserting a cut groove 24 along the axial direction until it reaches the core material 21. A mountain-shaped notch 24a that is open toward the outside is formed at the end of the cut groove 24 on the side of the portion 22a to which the adhesive 23 is not applied. It is also formed by cutting.

次に以上のように構成された本実施例の使用方
法につき説明する。 Next, a method of using this embodiment configured as above will be explained.

る。 With the attachment portion 2 rotatably attached to the grip 3 as described above, it is fitted into the core material 21 of the dust removal roller 20 from the side 22a where the adhesive 23 is not applied. Then, as the fitting progresses, the arm 6 is fitted while being slightly elastically deformed toward the inside, and eventually the protruding part 11 formed along the axial direction at the center of the arm 6 extends from the end thereof. Fitting begins from the inclined surface 11a. Since the diameter of the circle inscribed with the protruding part 11 is larger than the inner diameter of the core material 21, the protruding part 11 is fitted into the inner peripheral surface of the core material 21 while biting into it. And core material 21
The installation of the dust removal roller 20 is completed when the end of the dust removal roller 20 comes into contact with the protrusion 10 which is protruded outward from the grip 3 side of the arm 6 and serves as a stopper.

２を剥離すればよい。 Then, the adhesive 23 exposed on the surface of the dust removal roller 20 is rolled over clothing, etc., to adsorb and collect dust. If the dust has been sufficiently absorbed and the adhesive effect has weakened, insert your fingertip into the notch 24a and insert the uppermost adhesive sheet 2.
2 should be peeled off.

この時、切欠部２４ａは粘着剤２３が塗布され
ていない部分２２ａの部分に形成されているた

る。 At this time, since the notch 24a is formed in the part 22a where the adhesive 23 is not applied, only the exposed part of the adhesive sheet 22 is picked, and this part is separated into layers. Therefore, it is possible to reliably peel off one sheet at a time.

すべての粘着シート２２を使用し終つた場合に
は新しいごみ取りローラ２０と交換すればよい。 When all the adhesive sheets 22 have been used, they can be replaced with new dust removal rollers 20.

きる。 By the way, since the projections 9 are provided protruding along the axial direction on the inner surface of each arm 6 of the mounting part 2, it is strong against bending, and the dust removal roller can be kept fitted for a long period of time. Even after repeated attachment and detachment,
It does not deform, permanently maintains its elasticity, and can continue to elastically hold the dust removal roller 20.

又、突出部１１は芯材２１の内周面に強く食い
込んだ状態となつているため、ごみ取りローラ２
０と装着部２との間に相対的な回転は生じないか
らローラは確実に保持することができる。 In addition, since the protrusion 11 is strongly wedged into the inner circumferential surface of the core material 21, the dust removal roller 2
Since no relative rotation occurs between the roller 0 and the mounting portion 2, the roller can be held securely.

に行なえる。 As is clear from the above description, according to the present invention, the inner surface of the plurality of arms extending along the axial direction of the attachment part of the dust removal roller, which is formed as a spool-shaped frame rotatably supported on the grip. The reinforcing ridges are formed perpendicularly to each arm, so the resistance to bending is sufficiently large and there is no plastic deformation even when bending force is applied over a long period of time, making it easy to remove dust. The roller can be held securely.
