Further, since the width direction of the slide member 8 is regulated by the protruding wall 15 provided on the base 4 and the guide portion 23 provided on the cover 5, these members do not rattle during cleaning of a floor surface or the like.

The wiping member 2 is attached to the mounting head 1 by attaching both ends of the base cloth 2a of the wiping member 2 to the temporary fixing claws 16 of the wiping member.
The operation is simple because the base 4 and the cover 5 can be temporarily fixed to each other and pressed against each other. Further, the engagement between the base 4 and the cover 5 causes the wiping body grips (the wiping body push-in hole 11 and the wiping body pressing projection 21) provided therein to firmly grip the wiping body 2, thereby cleaning the floor and the like. The wiping body 2 attached to the head 1 is not displaced or detached during the operation.

When the dirty or worn wiping body 2 is to be replaced, the operating lever 3 protruding above the cover 5 is replaced.
When the members 1 and 31 are pressed against each other against the biasing force of the slide spring 32, the locking between the locking claw 14 and the locking claw 30 provided on the slide member 8 of the cover 4 and the cover 5 is released, and the erect member stands. Since the stays 6 and 6 are erected by the urging forces of the springs 7 and 7, the base 4 moves in a parallel state and separates from the cover 5. Therefore, the wiping body 2 can be easily removed from the mounting head 1. This operation of removing the wiping member can be performed above the cover 5 and it is not necessary to directly touch the dirty wiping member 2 with the hand, so that the operation is simple and the hands are not stained. After removing the dirty or worn wiping body 2, a new wiping body 2 can be mounted on the mounting head 1 by the above-described operation.
