A third group barrel 3 holding a third lens group L3 is 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 barrel 3, and a Y electromagnetic coil is disposed at a Y guide base 24 surrounding the third group barrel 3. As a driver in the pitch direction, a P magnet and P yoke 29 are fixed to the Y guide base 24, and a P electromagnetic coil is fixed to a P guide base at an opposed position. A Y guide bar 25 and a P guide bar 30 are 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. |
