A disk clamp comprising:
- a disk-shaped main body including a central axis line;
- an annular mounting groove provided in a first surface of the main body, in which a wire for unbalance adjustment is mountable;
- a plurality of through-holes formed through the main body and arranged to be spaced apart from each other equally in a circumferential direction around the central axis line, through each of which a fixing screw is insertable;
- a plurality of female threaded holes formed on the first surface of the main body and spaced apart from each other equally in the circumferential direction, into each of which an adjustment screw for balancing adjustment is screwable;
- and
- a washer provided on the first surface of the main body to be displaceable in a radial direction of the main body, wherein the adjustment screw is screwable into the female threaded hole via the washer provided on the first surface, and the washer is to be fixed to the main body by the adjustment screw in a state where the washer is positioned at an arbitrary radial position.
