PURPOSE: An optical pick-up actuator supporting structure is provided to generate symmetrical maximum strain in the event of a focusing operation and a tracking operation. CONSTITUTION: An optical pick-up actuator supporting structure includes an objective lens(33), a lens holder(31), and an elastic support member. The objective lens forms a light spot to read/write data information from/on an optical disc. The lens holder holds the objective lens and has a tracking coil, a focusing coil and a tilting coil attached thereto. The elastic support member supports the lens holder and applies a tracking signal, a focusing signal and a tilt signal to the lens holder. The elastic support member includes a focusing wire suspension(39a) that applies the focusing signal, a tracking wire suspension(39c) that applies the tracking signal, and a tilt wire suspension(39b) that applies the tilt signal and is deformed to have strong expensive force at the center.
