ABSTRACT:
In an objective lens driving device having a lens holder movably holding an objective lens, a damper base, and a suspension member elastically supporting the lens holder with respect to the damper base, the suspension member consists of four suspension wires disposed on both sides of the damper base and the lens holder. The damper base has first supporting portions for supporting one end of each suspension wire while the lens holder has second supporting portions for supporting another end of each suspension wire. The second supporting portions are apart from the first supporting portion by a first distance. The damper base has damper portions which are disposed between the first and the second supporting portions and which are apart from the first supporting portions by a second distance. The second distance is laid in a range between one-fifths and two-fifths of the first distance.
