PURPOSE:To obtain a stable oscillation characteristic, by providing a through hole on an elastic supporting member in a direction from a fixed supporting body to a lens holding means, and inserting with play a conductor for supplying a power with a diameter smaller than the inner diameter of the through hole in the through hole. CONSTITUTION:The through hole 20 is pierced in the inside of damping rubber 15' in the direction from a substrate 3 side to a drum 7 side. The conductor 19 with the diameter smaller than the inner diameter of the through hole 20 is inserted with play in the through hole 20. The conductor 19 is structured in such a way that the conductors with low rigidity are intertwisted and formation is performed by using a wire rod so as not to disturb the deformation of the damping rubber 15', and the wire rod whose total length is larger than that of the through hole 20 pierced in the inside of the damping rubber 15' is arranged in the inside of the through hole 20 unfastenedly. In such a way, it is possible to stabilize the oscillation characteristic (dynamic characteristic) of an objective lens driving device. |
