发明名称 Objective lens driving apparatus.
摘要 <p>In an objective lens driving apparatus (1) used in an optical information recording and reproducing apparatus or the like, a vibration is suppressed and a resonance peak on transfer function is suppressed when movable portions (2, 3) are moved in focusing and tracking directions and when these portions are turned around focusing and tracking directions. An elastic body (5) which supports the movable portions (2, 3) movably in two directions, i.e., focusing direction and tracking direction to a fixed portion (4) includes a bent portion (5c) in an intermediate portion between the side of movable portion (5f) and the side of fixed portion (5g). A damper member (6) is adhered to bridge a gap between a branched arm portion (5d) branching from a linear portion (5a) extending from the side of movable portion (5f), and a fixed portion (5e). The bent portion (5c) couples two linear portions (5a) and (5b) which are not on the same line. &lt;IMAGE&gt;</p>
