In addition, even if the material itself is not the above-mentioned material, for example, the surface is made rough while using the same ABS resin as the other parts of the head part 1 and the like, and the smoothness is lowered by forming fine irregularities. By doing this, the frictional resistance generated with the cleaning sheet P may be increased.

The high friction portion 14 can adopt any configuration as long as it can increase the frictional resistance as compared with other portions on the upper surface of the head portion 1, but the surface roughness is 0.8 μm to 2.5 μm. Is preferable, and more preferably 1.0 μm or more and 2.0 μm or less. In addition, as long as the surface roughness is in this numerical range, any specific material may be used.
If the surface roughness is smaller than 0.8 μm, the frictional resistance generated with the cleaning sheet P is not sufficient. If the surface roughness is larger than 2.5 μm, the risk of the cleaning sheet P breaking is increased. Not desirable.

The surface roughness in this case is not a test piece of the same material but a value measured according to JIS B 0601-1982 in a state where the high friction portion 14 is provided on the top surface portion 11.
The surface roughness represents the deviation in the vertical direction of the object surface, and it is a well-known fact that the larger the surface roughness, the higher the value of the surface roughness, the higher the frictional resistance. The surface roughness of the portion 14 defines its preferred embodiment.

As shown in FIG. 1, the high friction portion 14 is formed in a band shape so as to connect the attachment portion 13 in a plan view, and is formed to have a width of 10 mm to 40 mm, more preferably 15 mm to 25 mm.

The high friction portion 14 may be formed on the mounting portion 13 by increasing the frictional resistance on the upper surface side of the claw portion 131 of the mounting portion 13. For example, the high friction portion 14 can be formed also on the mounting portion 13 by forming the claw portion 131 by EVA resin having a large frictional resistance similar to that used for the high friction portion 14.
Alternatively, the high friction portion 14 may be provided only on the mounting portion 13, and the high friction portion 14 may not be provided on the other portion of the top surface 11.

(Effect of the embodiment)
According to the present embodiment, the high friction portion 14 is formed on the upper surface side of the head portion 1 so that the cleaning sheet P slips when the cleaning sheet P is attached to the head portion 1 using the attachment portion 13. It becomes difficult.
As a result, the force transmitted from the handle can be sufficiently transmitted to the cleaning sheet, and thus the efficiency of cleaning can be improved.

In particular, as shown in FIG. 2, the upper surface of the head portion 1 has a large effect due to the curved surface shape in which both end portions rise in the longitudinal direction.

In addition, when the high friction portion 14 is formed of a soft material, the portion where the height of the upper surface of the head portion 1 becomes high becomes soft, so when cleaning the narrow space under the furniture etc. The effect of making it hard to damage can also be obtained.

Further, by providing the high friction portion 14, the cleaning sheet P is less likely to shift even if the strength of the claw portion 131 of the mounting portion 13 is low, so that the claw portion 131 can be formed relatively soft. Removal of the cleaning sheet P is facilitated.

Further, when the high friction portion 14 is formed also on the mounting portion 13, the area of the high friction portion 14 is increased, so that the effect can be enhanced. In addition, when the high friction portion 14 is formed only on the mounting portion 13, there is no need to perform processing other than forming the mounting portion 13 on the top surface portion 11, so that the cleaning tool 100 can be manufactured. It becomes easy.
