When one shaft member 102 is viewed from the tip side, the locus connecting the tips of the brush bristles 103 has a substantially circular shape as shown in FIG. 6B.
The fixing portion 104 is a portion that fixes the tips of the plurality of shaft members 102 to each other.

[Dimensional relationship between the cleaning space and the brush for washing up the pedestal]
Next, the dimensional relationship between the cleaning space Sp and the brush 100 for cleaning the raising base will be described with reference to FIGS. 3, 4, 6A, and 6B.
The width dimension d1 (FIG. 6A) of the plurality of brush bristles 103 is set to about 2.8 to 4.2 mm. The width dimension d1 is set to be larger than the width dimension (length dimension along the rotation axis RAx) D1 (FIG. 4) of the cleaning space Sp.
The thickness dimension d2 (FIG. 6B) of the plurality of brush bristles 103 is set to about 0.6 to 1.2 mm. Then, the thickness dimension d2 is set to be larger than the gap dimension D2 (FIG. 4) between the bottom portion 123 and the raising base 13 in the cleaning space Sp (uniform portion Sp1).
Furthermore, the length dimension d3 (FIG. 6A) of the plurality of brush bristles 103 is set to about 8 to 20 mm. The length dimension d3 is set to be larger than the length dimension of the cleaning space Sp (length dimension connecting the openings at both ends) D3 (FIG. 3).

According to the raising stand cleaning brush 100 according to the present embodiment described above, the following effects can be obtained.
7A and 7B are diagrams for explaining the effect of the present embodiment. Specifically, FIG. 7A is a cross-sectional view corresponding to FIG. FIG. 7B is a sectional view corresponding to FIG.
The raising base cleaning brush 100 according to the present embodiment includes a handle 101, a plurality of shaft members 102, and a plurality of brush bristles 103. The cleaning space Sp and the raising table cleaning brush 100 have the above-described dimensional relationship. Therefore, as shown in FIGS. 7A and 7B, for example, if the raising base cleaning brush 100 is inserted into the cleaning space Sp from the distal end side of the insertion portion 6, the raising base cleaning brush 100 is connected to the distal end of the cleaning space Sp. Can be penetrated from the side to the proximal side. Further, the tips of the plurality of brush bristles 103 can be brought into contact with the entire wall surface forming the cleaning space Sp. Then, if the brush 100 for cleaning the raising base is moved back and forth in the cleaning space Sp, the brush 100 for cleaning the raising base can collectively brush the entire gap between the bottom portion 123 and the raising base 13.
Therefore, according to the raising base cleaning brush 100 according to the present embodiment, it is possible to simplify the cleaning work and reduce the work time required for cleaning.

Further, in the raising table cleaning brush 100 according to the present embodiment, the handle 101 has a flat plate shape. A plurality of shaft members 102 are provided on the side end portion 101A. For this reason, for example, when inserting the brush 100 for cleaning the raising base into the cleaning space Sp from the tip side of the insertion portion 6, the handle 101 can be positioned up to the vicinity of the introducing portion Sp2 in the cleaning space Sp, and the cleaning for the raising base can be performed. It is possible to increase the moving distance of the brush 100 for moving back and forth. Therefore, it is possible to downsize the raising base cleaning brush 100 without unnecessarily increasing the length dimension of the plurality of shaft members 102 (the plurality of brush bristles 103).

Further, in the raising base cleaning brush 100 according to the present embodiment, the plurality of shaft members 102 are arranged such that the plane PL4 including the plurality of shaft members 102 is parallel to the plate surface PL5 of the handle 101. Has been done. Therefore, the user can easily insert the raising table cleaning brush 100 into the cleaning space Sp by only checking the posture of the handle 101.

Further, the brush 100 for cleaning the raising base according to the present embodiment further includes a fixing portion 104 that fixes the tips of the plurality of shaft members 102 to each other. Therefore, even when the brush 100 for cleaning the elevator base is used for a long period of time, the tips of the plurality of shaft members 102 are prevented from being separated from each other, and the brush 100 for cleaning the elevator base to the cleaning space Sp is prevented. The insertability of can be maintained well.
