PROBLEM TO BE SOLVED: To reduce the operation sound of an optical disk device, especially an operation sound caused by the vibration of the yoke of an objective lens actuator. SOLUTION: A yoke part is held in an actuator holder by a bent plate spring in with freedom in at least two directions, and the actuator holder is bonded and connected to a head case. Alternatively, the yoke part is held in the head case by a coil spring or the like in the state of freedom in at least two directions, and the actuator holder is bonded and connected to the head case. Thus, the transmission of the vibration of the yoke to the head case is made difficult, and an operation sound caused by an objective lens actuator is reduced. COPYRIGHT: (C)2006,JPO&NCIPI
