摘要：
A chucking device includes a disk support unit on which a disk is placed, a resin-made turntable arranged to directly or indirectly support the disk support unit from below, a metal member including a circular plate portion closely secured to a lower surface of the turntable, and a plurality of balls rollably arranged below the disk support unit and above the circular plate portion about a center axis in a circumferential direction. The turntable includes an antiskid member, a bottom rolling surface arranged to support the balls from below through the antiskid member and a cylindrical side rolling surface positioned radially outwards of the balls.
