Abstract
A disk device (10) comprises a case (11) for supporting the entire disk device (10), a base chassis (12) on which a spindle motor (21) for rotating the disk is set, a counterweight (13) for absorbing vibration of the base chassis (12), and a plurality of elastic bodies (14a-14d) for mutually supporting the case (11), the base chassis (12) and the counterweight (13). The case (11), the base chassis (12), and the counterweight (13) are supported by the common elastic bodies (14a-14d). As a result, there can be provided the dynamic vibration absorber in which the number of parts is not increased and a cost can be reduced, and the optical disk device (10) using the dynamic vibration absorber.
