Abstract
In a disk apparatus for driving a recording disk medium, a spindle motor is provided with a rotary shaft. A chucking table, on which the recording disk medium is mounted, includes a support integrally formed with a support base having a supporting face which supports the recording disk medium, a cylindrical bearing part, into which the rotary shaft is fitted, extending from the support base in parallel with the rotary shaft, and an annular abutment part extended from the support base in parallel with the bearing part, to be abutted against an inner periphery of the recording disk medium. The chucking table includes at least one claw member provided in an outer periphery of the abutment part, and an urging member disposed between the claw member and the bearing part so as to retractably urge the claw member outwards in a radial direction of the recording disk medium.
