A floor care disk for a floor care machine such as a floor polishing machine includes a floor care pad mounted on a drive plate. The drive plate includes a stiff disk element and tongue-like tabs connected flexibly to a radially outer portion or rim of the disk element, and extending radially inwardly toward a radially inner portion or hub of the disk element. The radially inner free ends of the tongue-like tabs are free to flexibly deflect away from the plane of the disk element. The pad is mounted on the tabs and on the radially outer portion of the disk element. During rotational operation of the floor care disk, due to the arising centrifugal force acting on the center of mass of the rotating pad and tongue-like tabs, the pad and the tongue-like tabs are flexibly deflected away from the disk element and toward the floor surface, thereby deflecting the pad into osculating contact with the floor surface. |
