摘要：
An object lens drive unit in which an undesired displacement or inclination of an object lens with respect to an optical disc is reduced. The position at which a lens holder for the object lens is supported by a pair of rod-shaped elastic support members in the focusing direction substantially coincides with the center of the tracking coil in the focusing direction.
