Fig. 3 is a perspective view of the brush structure with the lid attached to the main body so as to cover the brush, and Fig. 4 is a perspective view of the brush structure with the lid attached to the main body from the opposite side of the brush. is.

[0020] The brush structure 1 according to this embodiment includes a main body portion 10 having at least one surface 11, and a brush portion 20 provided on the surface 11 of the main body portion 10 and made up of a plurality of bristles 21.

[0021] The main body 10 has a rectangular parallelepiped shape with a notch 12 provided on one side, and the brush part 20 is provided on one surface 11 of the rectangle.

[0022] Furthermore, the main body 10 is the portion of the brush structure 1 that is grasped by the user, and is provided with a non-slip surface 14 on the side surface 13 adjacent to the long side of the surface 11 on which the brush portion 20 is provided. The non-slip surface 14 may be formed of a plurality of hemispherical depressions, for example, as shown in FIG. 1. Note that the non-slip surface 14 may have other shapes and is not necessarily provided. Furthermore, the cutout portion 12 is provided to make it easier for the user to grasp the main body 10, and is not necessarily provided.

[0023] An engaged portion 15 is provided on the side surface 13 of the main body 10 to engage with an engaging portion 41c provided on the lid portion 40, which will be described later, and to fix the lid portion 40. In this embodiment, the engaged portion 15 is formed in a groove shape extending along the long side of the side surface 13.

[0024] The bristles 21 of the brush part 20 of this embodiment have different length dimensions from one end 11a to the other end 11b of the surface 11 on which the brush part 20 is provided. Specifically, the bristles 21 gradually become longer from the one end 11a to the other end 11b.

[0025] 1, the bristles 21 have a length dimension such that the tips of the bristles curve from one end 11a to the other end 11b, and are trimmed to form a curved surface at the tips of the bristles 21 that make up the brush portion 20. The curved surface formed by the tips of the bristles 21 that make up the brush portion 20 can be any curved surface, for example, a circular arc, hyperbolic, sinusoidal, or other curved surface in cross section in a direction perpendicular to the long side of the surface 11, and may also be a curved surface that follows the side surface of the tire.

[0026] The number of hairs 21 is 2000 / cm on the surface 11. 2 Over 5000 pieces / cm 2 It is preferable that the bristles 21 are provided at a density of 0.07 mm or less, and more preferably at a uniform density on the surface 11. The thickness (diameter) of the bristles 21 is preferably 0.07 mm or more and 0.1 mm or less. The material of the bristles 21 is arbitrary and may be natural or artificial, for example, polybutylene terephthalate (PBT).

[0027] Furthermore, it is preferable that the length of the bristles 21 exposed from the main body 10 is in the range of 3 mm to 25 mm. In the present embodiment shown in Fig. 1, it is preferable that the length of the bristles 21 exposed from the main body 10 is 3 mm at one end 11a of the surface 11 and 25 mm at the other end 11b.

[0028] The brush structure 1 according to this embodiment further includes a lid 40 that fits into the main body 10 from the brush part 20 side and covers the brush part 20. As shown in Fig. 2, the lid 40 has a substantially rectangular box-shaped part 41 having an opening 41a on one side, and an introduction part 42 that is provided around the opening 41a of the box-shaped part 41 and extends from the box-shaped part 41.

[0029] Of the peripheral walls surrounding the opening 41a of the box-shaped portion 41, peripheral wall 41b on the long side of the opening 41a is provided with an engaging portion 41c that can engage with the engaged portion 15 of the main body 10. Figure 3 shows the state in which the lid portion 40 covers the brush portion 20. When the lid portion 40 covers the brush portion 20, the engaging portion 41c engages with the engaged portion 15.

[0030] Furthermore, it is preferable that the lid portion 40 can be fitted to the main body portion 10 from the side opposite the brush portion 20. Figure 4 shows a state in which the lid portion 40 is fitted to the main body portion 10 from the side opposite the brush portion 20. In this case, it is preferable that the lid portion 40 is fitted to the main body portion 10 in a state in which a part of the main body portion 10 is exposed.

[0031] According to the brush structure 1 of this embodiment, the bristles 21 of the brush portion 20 have different length dimensions on one end 11a side and the other end 11b side of the surface 11. As a result, the shorter length portion has relatively greater elasticity (so-called stiffness) than the longer length portion, and when the brush structure 1 is used to clean tires, the shorter length portion has a higher cleaning power. Furthermore, when the brush structure 1 is used to apply wax to tires, more wax can be attached to the longer length portion than to the shorter length portion, so more wax can be applied to the tire on the shorter length portion than on the shorter length portion.

[0032] Furthermore, the brush structure 1 according to this embodiment has bristles 21 whose tips form curved surfaces, making it suitable for cleaning the curved surfaces of tire sides or for applying wax to tire sides.

[0033] The brush structure 1 according to this embodiment has a density of bristles 21 of 2000 pieces / cm 2 Over 5000 pieces / cm 2 It is preferable that the number of bristles 21 is equal to or less than 1 / 2 mm, that they are arranged at a uniform density, and that the length of the portion of the bristles 21 exposed from the main body 10 is in the range of 3 mm to 25 mm. By satisfying each of these conditions, the brush structure 1 not only has a higher cleaning power and a higher wax application efficiency, but also makes it easier to clean the tire without damaging it and to apply wax to it.

[0034] The brush structure 1 according to this embodiment includes the lid portion 40, which can protect the brush portion 20 when the brush structure 1 is not in use. Furthermore, when the brush structure 1 is in use, the lid portion can be fitted to the main body portion 10 to prevent the lid portion 40 from being lost and also protect the inside of the lid portion 40.
