ABSTRACT:
A third group barrel3holding a third lens group L3is controlled to be driven by drivers in yaw and pitch directions orthogonal to an optical axis, respectively. The Y magnet and the Y yoke of the driver in the yaw direction are fixed on the third group barrel3, and a Y electromagnetic coil is disposed at a Y guide base24surrounding the third group barrel3. As a driver in the pitch direction, a P magnet and P yoke29are fixed to the Y guide base24, and a P electromagnetic coil is fixed to a P guide base at an opposed position. A Y guide bar25and a P guide bar30are overlapped with projection regions onto planes orthogonal to the optical axis of the Y electromagnetic coil and the Y magnet, and the P electromagnetic coil and the P magnet, respectively.
