ABSTRACT:
The invention provides increased stroke of the clamper and a reduction in thickness of the entire disk device by improving structures of a clamper for clamping the recording medium to turn freely and a clamper plate engaging with the clamper. Plural connecting sections that connect an inner torus and an outer torus, plural L-shaped hook sections at an upper end of an inner rim wall of substantially a cylindrical shape extended upward from a border of the connecting sections and the outer torus, and an outer rim wall of substantially a cylindrical shape extended upward from the outer torus are integrally formed on a clamper body. Engaging holes engaging with the L-shaped hook sections are provided in a clamper plate. A step section, an outer peripheral side of which is high, is provided in a position where an upper end of the outer rim wall collides with the clamper plate.
