摘要：
A lens barrel comprising: a plurality of lens groups including two lens groups for guiding object light; and a lens drive apparatus for moving the two lens groups in the plurality of lens groups in a direction of an optical axis, the lens drive apparatus includes a single motor and a lead screw rotated by the rotation of the motor; wherein the lens drive apparatus is structured in such a manner that one lens group of the two lens groups is moved linearly to the rotation of the lead screw, and the other lens group of the two lens groups is moved non-linearly to the rotation of the lead screw.
