ABSTRACT:
Shafts are fixed to a base and extend in a direction parallel to a center axis of a through hole of the base. Two yoke arrangements are installed to the shafts. A lens holder frame holds a lens, which has an optical axis parallel to the central axis of the through hole of the base. The lens holder frame is axially placed in a space between the two yoke arrangements and is swingably supported by a plurality of wire springs, which are fixed to the base. Drive coils are fixed to the lens holder frame and generate a drive force to move the lens holder frame.
