In an optical disk device (1), the generation of noises can be avoided even when a pressure or any other stress is applied to the wall of the housing (50) of the optical disk device, and the wall of the housing is caused to come into contact with a disk retaining assembly (11) of the optical disk device that may be rotating. A shaft (32) projecting centrally from the optical disk retaining assembly and the opposing wall of the housing is provided with a spherical tip (32a) at a free end thereof.
