Chucking apparatus for a disk player

摘要

A chucking apparatus 1 includes a chuck disk 11 and a chuck arm 17. The disk 11 is a disk lockable with a turn table 3. The arm 17 has an opening 33 through which the chuck disk 11 is insertable, and a holding part 31 where the disk 11 is rotatably arranged, plural first hooks 35 projecting inwardly radially from an edge of the opening 33, and a second hook 37 provided at the edge of the opening 33 for preventing the disk 11 in the part 31 from escaping outward. The hooks 35 allow insertion of the disk 11 in the part 31 and support the disk 11 in the part 31. The second hook 37 is shaped to have rigidity against a force received when the disk 11 tends to escape from the holding part than that against a force received when the disk 11 is mounted.
