Objective lens drive device for optical pick-up

An objective lens driving apparatus for an optical pickup includes a blade (20) on which an objective lens (10) is mounted, a plurality of elastic support members (W1-W6) supporting the blade (20) and capable of elastically moving with respect to the blade (20), and a servo mechanism driving the blade up and down, left and right, and in a rotational direction. The elastic support members (W1-W6) are grouped into pairs of the elastic support members arranged to face each other with respect to a center of rotation of the blade, and distances between the elastic support members in the respective pairs are identical. Thus, by almost removing a difference in the amount of deformation between the elastic support members supporting the blade during tilt control, the elastic support members are prevented from being moved in arbitrary directions when a small impact or vibration is applied or generated. Thus, the control of the position of the objective lens can be stably performed.
