ABSTRACT:
The present invention is relative with an objective lens driving device used in an optical pickup device, and includes a stationary unit, a lens bobbin provided with an objective lens, at least one magnet provided on one of the lens bobbin and the stationary unit, a coil unit provided on the other of the lens bobbin and the stationary unit for causing movement of the lens bobbin in a direction parallel to the optical axis of the objective lens and in a planar direction perpendicular to the optical axis of the objective lens, and an elastic supporting unit of a stainless material, provided between a stationary unit and the lens bobbin. The elastic supporting unit supports the lens bobbin for movement in a direction parallel to the optical axis of the objective lens and in a planar direction perpendicular to the optical axis of the objective lens.
