装置。[Claims for Utility Model Registration] An optical disk device having a disk hub consisting of a ring-shaped member made of synthetic resin fixed to the center of a disk substrate, and a metal plate for a magnetic clamp attached to this ring-shaped member. In this step, the joint formed on the inner peripheral edge of the metal plate is joined by a groove formed on the inner peripheral side of the ring-shaped member, and a plurality of engaging protrusions formed protrudingly formed on the outer peripheral edge of the metal plate are connected to the ring-shaped member. A disk hub is constructed by attaching a metal plate to the ring-shaped member by engaging and locking the engaged portion formed at a position corresponding to the engaging protrusion on the outer circumferential side of the ring-shaped member. optical disk device.
