<P>PROBLEM TO BE SOLVED: To provide an optical pickup device having such constitution that invasion of dust to a gap between an actuator of a lens holder and a housing is reduced as much as as possible. <P>SOLUTION: The actuator 6 has a yoke base in which a magnet holding part and a supporting part for lens holder 5 are formed by blanking and louvering a metal plate, and the yoke base has such structure that it is fixed to the housing through an attitude adjusting mechanism. A supporting plate 29 supporting the lens holder 5 by a wire and a flexible printed circuit board 33 having wiring connected electrically to the wire 7 are fixed to the supporting part of the lens holder composed of raising pieces formed at the yoke base. A gap between the supporting plate 29 and the housing 1 is blockaded by a connecting part 33a formed at a part of the housing 1 side from a fixed part for the supporting plate 29 of the flexible printed circuit board 33 and having wide width thereby preventing the ingress of dust form the gap. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
