とを特徴とする対物レンズ駆動装置の配線構造。[Claims for Utility Model Registration] A lens support member that supports an objective lens whose optical axis is perpendicular to the disk recording surface is supported by an intermediate support via a tracking movable body that is movable only in the radial direction of the disk, The intermediate support is supported by a fixed support via a focus movable body that is movable only in a direction perpendicular to the disk recording surface, and the lens support member is supported by a tracking drive section interposed between the fixed support and the lens support member. an objective lens drive device configured to drive the disk in a radial direction and drive the intermediate support in a direction perpendicular to the recording surface of the disk by a focus drive section interposed between the fixed support and the intermediate support. In the wiring structure, a terminal block is fixed to the lens support member and/or the intermediate support, one end of the coil winding wire of the tracking drive section and/or the focus drive section is connected to this terminal block, and the terminal block is connected to the terminal block. A wiring structure for an objective lens drive device, characterized in that a conductive wire having lower rigidity than the coil winding wire is connected, and power is supplied to the coil of the tracking drive unit and/or the focus drive unit via this conductor wire. .
