An inner rotor type motor includes a turn table having a disk loading portion and a central opening portion arranged to allow a disk to be attached thereto and removed therefrom, a rotor concentric with a rotation axis of the turn table, the rotor including a rotor holder having therein a rotor magnet and a cylindrical portion arranged to retain on an outer circumferential surface thereof the rotor magnet, and a stator having an armature arranged to oppose an outer circumferential surface of the rotor magnet via a gap therebetween. The turn table is affixed in an axial direction on an upper portion of the rotor holder, and the disk loading portion is arranged radially outside the cylindrical portion of the rotor holder. A disk loading surface of the disk loading portion is arranged to make contact with the disk, and a bottom portion of the disk loading portion is arranged axially below an area where the turn table and the rotor holder make contact with one another. The disk loading portion has a predetermined thickness in the axial direction, thereby preventing a deformation of the disk loading portion even when the disk is placed thereupon.
