As shown in FIGS. 1 to 6, the mounting portion 2 is formed as a thread-shaped frame as a whole, and a short cylindrical shaft bearing portion 4 is provided in the center of the mounting portion 2.
A plurality of connecting pieces 5 are provided to protrude from the outer peripheral surface of the connecting piece 5 and extend integrally therewith at equal angular intervals in the circumferential direction. The connecting piece 5 is formed over the entire length of the shaft bearing part 4 in the axial direction, and elongated arms 6 each having an arcuate cross section are connected to the outer ends thereof. It is integrally provided with the width direction perpendicular to the piece 5.

The arms 6 are connected by arcuate pieces 7 as shown in FIGS. 1 and 5. and,
As is clear from the cross-sectional view of FIG. 2, this arc-shaped piece 7 is provided on a circumference concentrically with respect to the shaft bearing part 4, and its outer peripheral surface has an arc-shaped cross section. It is on the same circumference as 6.

Further, a fan-shaped connecting piece 8 is formed in the center of the shaft bearing part 4 in the axial direction and is perpendicular to the axial direction and is integrated with the inner peripheral surfaces of the connecting pieces 5, 5 and the circular arc-shaped piece 7. ing.

A protrusion 9 is formed on the inner surface of each arm 6 and extends integrally from the connecting piece 5, and the tip of the protrusion 9 extends outward from the tip of the arm 6. The tip is formed into an arc shape.

Furthermore, a projecting piece 10 is provided at the rear end of each arm 6 so as to project outwardly at a right angle.

Furthermore, a protrusion 11 having a substantially triangular cross section is provided at the center of each arm 6 on its outer circumferential surface along the axial direction and at a position substantially corresponding to the arcuate piece 7 . Both ends of these protrusions 11 form inclined surfaces 11a.

The center hole of the shaft bearing part 4 has a large diameter part 12 formed on the rear end side of the arm 6, and a small diameter part 13 formed on the tip side, and both are continuous through a tapered part 14 at approximately the center in the axial direction. are doing.

On the other hand, as shown in each figure, the grip 3 has a structure that is curved upward to make it easier to grip, and its cross-sectional shape is approximately U-shaped with an open downward direction.
It has a letter-shaped cross-section.

At the tip of this grip 3 are shown figures 3 and 4.
As shown in FIG. 11, a partition wall 3a is provided with the left and right side walls connected, and a reinforcing rib 3 is provided between the side surface of the partition wall 3a and the end wall 3b of the grip 3.
c, and a through hole 3d for hanging is formed at the rear end of the grip 3.

A support frame 15 projects from the end wall 3b at the tip of the grip 3 in a manner perpendicular to the end wall 3b.
The support frame 15 has an approximately cross-shaped cross-sectional shape, and the large-diameter portion of the shaft bearing portion 4 is attached to the distal end of the support frame 15 via a disk portion 16 as shown in FIGS. 3, 4, and 7. A shaft 17 rotatably fitted into the large diameter portion 1
The length of the shaft 17 is approximately the same as the length of the shaft 17, and furthermore, two protruding pieces 18, 18, which are split into a forked shape, are protruded from the tip of the shaft 17. Projections 19, 19 are provided at the tips of these protrusions 18, 18, respectively, and the protrusions 19, 19 become lower as they reach the tips, protruding outward.
It becomes a. The distance from this upright wall 19a to the tip of the shaft 17 is approximately equal to the length of the small diameter portion 13 of the shaft bearing portion 4, as shown in FIG. Further, the outer circumferential surface of each protruding piece 18, 18 is a circular arc-shaped surface on the circumference having a diameter equal to the inner diameter of the small diameter portion 13, and the outer circumferential surface of the protruding portion 19 is also formed in a circular arc shape.

Grip 3 has the above structure, so
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.

By the way, what is indicated by the reference numeral 20 in FIGS. 10 and 11 is a dust removal roller, and this dust removal roller 20 has a hollow core material 21 made of cardboard or the like. The inner diameter of the hollow core material 21 is slightly shorter than the diameter of the circle inscribed with the protrusion 11 provided in the center of each arm 6 of the mounting portion 2, and
The length of arm 6 is approximately equal to the total length of arm 6.

An adhesive sheet 22 is wrapped around this core material 21. This adhesive sheet 22 is made by applying an adhesive 23 to the outer peripheral surface of a base made of paper, synthetic resin sheet, film, etc., and is wound around the base many times. Adhesive 23 of adhesive sheet 22
A release agent is applied to the back side that is not coated to make it easier to remove.

A portion 22 where the adhesive 23 is not applied to one end side of the adhesive sheet 22 of the dust removal roller 20
A is formed with a predetermined width over the entire circumference.

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.

Next, a method of using this embodiment configured as above will be explained.

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.

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.

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.

When all the adhesive sheets 22 have been used, they can be replaced with new dust removal rollers 20.

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.

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.

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.

In addition, since a protrusion is formed along the axial direction in the center of the arm of the attachment part in the axial direction and has inclined surfaces at both ends, this protrusion is formed on the inner peripheral surface of the core material of the dust removal roller. There is no relative rotation between the dust removal roller and the mounting portion, and the dust removal roller can be held securely.
