The apparatus includes a central boss which is coupled to a rotating shaft of a motor, a guide which extends from the central boss outwards and is inserted into a center hole of a disk, and a chucking unit which extends from the central boss outwards. The chucking unit is elastically deformable inwards when pushed by the disk that is fitted over the guide. The chucking unit includes a lower horizontal part, a vertical part and an upper horizontal part. The lower horizontal part extends from the lower portion of the central boss outwards in the horizontal direction. The vertical part is bent from the outer end of the lower horizontal part upwards. The vertical part extends in a direction inclined outwards. The upper horizontal part extends from the upper end of the vertical part inwards in a horizontal direction.
