Abstract
Lens barrel 3 includes a stationary frame 20, a drive frame 30, a rotation cam frame 70, and a first lens frame 60. The drive frame 30 is supported by the stationary frame 20 to be movable in a Y axis direction along an optical axis of an imaging optical system O and rotatable around the optical axis in response to a drive force. The rotation cam frame 70 is supported by the drive frame 30 to be movable in the Y axis direction relative to the drive frame 30 in response to the drive force. The first lens frame 60 supports a first lens group G1 included in the imaging optical system O, and is supported by the rotation cam frame 70 to be movable in the Y axis direction relative to the rotation cam frame 70 in response to the drive force.
