LENS BARREL, IMAGING APPARATUS, AND OPTICAL DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a lens barrel realizing the facilitation of the positional adjustment of a guide shaft for guiding the movement of a lens in an optical axis direction, and an imaging apparatus and an optical device using the lens barrel. SOLUTION: A lens frame 61 is housed in a lower lens barrel 32 and its movement in the optical axis direction is guided by guide shafts 62 and 63. An adjusting lever 80 has a lever main body 83 where a bearing part 81 to bear the lower end of the guide shaft 62 and an insertion hole 82 to insert an adjusting pin 90 through are formed, and a grasping part 84 extended to project from the insertion hole 82 side of the lever main body 83 to the outside of the lower lens barrel 32. The adjusting lever 80 is held to freely move on a plane perpendicular to an optical axis L2 with the adjusting pin 90 as a fulcrum by the lower lens barrel 32. A distance LA between the edge of the grasping part 84 and the insertion hole 82 is set to be longer than a distance LB between the insertion hole 82 and the bearing part 81.
