<P>PROBLEM TO BE SOLVED: To provide a lens barrel in which degradation of optical performance is prevented. <P>SOLUTION: A lens barrel 100 includes a vibration-proof unit 200 that includes: a base frame 210 that is suspended by a main guide bar 141 and a sub guide bar 142; a vibration-proof lens holding frame 220 that holds a vibration-proof lens L4 and is movable in two directions orthogonal to each other with respect to the base frame 210; and a first voice coil motor 250Y and a second voice coil motor 250X that move the vibration-proof lens holding frame respectively in the two directions with respect to the base frame. In the vibration-proof unit 200, the first voice coil motor and the second voice coil motor are disposed on one side of a first linear line passing through the main guide bar and the sub guide bar. In a first region among four divided regions divided by the first linear line and a second linear line that is orthogonal to the first linear line and passes through the center of the lens, the first voice coil motor is disposed at a position closer to the first linear line than the second linear line. <P>COPYRIGHT: (C)2013,JPO&INPIT |
