The edge portion of the cleaning sheet S, whose edge portion on the long side 1i side is engaged with the tooth portion 1k, is turned so that the detached edge portion of the cleaning sheet S is turned downward to cover the upper surface plate 1a, and the tooth portion on the long side 1g side is placed. Lock to 1k.

In this way, the cleaning sheet S soiled by use on the bottom plate 1b is turned inside out so that the clean surface is exposed on the top plate 1a side, and the handle portion 4 rotated to the bottom plate 1b side on the opposite side is turned over. The cleaning sheet S covering the upper surface plate 1a facing downward can be used for cleaning.

After the front and back sides of the cleaning sheet S have been fully used, the cleaning sheet S is removed from the four pairs of tooth portions 1k of the head portion 1 and replaced with a new cleaning sheet S.

Therefore, unlike the conventional cleaning sheet S, it is possible to turn over the cleaning sheet S in a state in which one edge portion side is locked, unlike the conventional cleaning sheet S which is once removed, turned over, and then reattached. In addition, the number of places where a hand touches the cleaning sheet S is reduced, and the hands are less likely to get dirty.

Further, in place of the holding portion consisting of a plurality of elastic tongue pieces arranged at the four corners of the top surface of the head portion of the conventional cleaning tool, concave portions are provided at the four corners of the top surface of the head portion, and the openings of the concave portions are used as the above-described second cleaning tools. A tooth portion 1k consisting of 1, 2nd trapezoidal teeth 1l and 1m may be arranged, or the tooth portion 1k may be employed for a cleaning cloth holding mechanism of an appropriate cleaning tool.

According to the cleaning tool of the present invention, the first and second trapezoidal teeth 1l and 1m provided on the head portion 1 and intersecting in the upper and lower directions are used as locking portions for the cleaning cloth, so that the cleaning sheets having different thicknesses can be cleaned. S and a dust cloth can be locked, and these can be easily attached and detached.

Further, the tooth portion 1k composed of the first and second trapezoidal teeth 1l and 1m, which are in contact with each other at one point of contact on the oblique sides of the trapezoid, has an appropriate clamping force, and the cleaning cloth is pulled from the locking portion during cleaning. It becomes difficult to come off, and when removing the cleaning cloth, it is difficult to get caught and can be easily removed.

In addition, while the holding portion of the conventional cleaning tool is an integrally molded product, the first and second trapezoidal teeth 1l and 1m are not integrally molded but are separately molded. It is possible to arrange them without creating a gap between them. Therefore, compared with the conventional cleaning tools, the holding force for the cleaning cloth can be increased.
