Abstract
A disk clamper () includes a clamper main body () and a lid body () that holds an attraction member () such as a magnet or the like between the clam main body () and the lid body (). The clamper main body () includes a peripheral wall () whose outer peripheral surface constitutes a cylindrical surface. The lid body () includes a peripheral wall () fitted on the outside of the peripheral wall () of the clamper main body (). Engaging claws () are formed on and protruded from the outer peripheral surface of the peripheral wall (). Engaging claws () are formed on the inner peripheral surface of the peripheral wall (). The clamper main body () and the lid body () can be integrated by fitting the peripheral wall () to the outside of the peripheral wall () in a state where the circumferential positions of the engaging claws. () are different from each other, and by rotating the peripheral walls () relative to each other until the engaging members () engage each other in the axial direction.
