The present invention is directed to an object lens drive device adapted
for moving an object lens in a focus direction of optical axis direction
and in a tracking direction perpendicular to the optical axis direction,
and includes a fixed position provided in such a manner that a supporting
shaft is projected, a movable portion comprised of an object lens, and a
bobbin adapted so that the object lens is attached and a hole through the
supporting shaft is inserted is formed, the bobbin being supported
movably along the supporting shaft and rotatably with the supporting
shaft being as center, a drive portion including a magnet portion
provided at either one of the fixed potion and the movable portion, and a
coil portion provided at the other portion to move the movable portion
along the supporting shaft to thereby move the object lens in the focus
direction, and to rotate the bobbin with the supporting shaft being as
center to thereby move the object lens in the tracking direction, and
supporting means including a magnetic member for supporting the movable
portion in the state inclined with respect to the supporting shaft.
