| Zusammenfassung: | A clamp device that clamps a disc onto a spindle motor that rotates the disc includes a clamp ring stacked on the disc and clamps the disc onto the spindle motor, a screw that fixes the clamp ring onto the spindle motor, and an axial force adjuster that nonlinearly changes a relationship between a tightening force of the screw and an axial force actually applied to the disc, and includes an elastic part that has a spring constant smaller than that of the clamp ring. |
