LENS BARREL AND IMAGING APPARATUS

PROBLEM TO BE SOLVED: To provide a lens barrel that enables an optical axis-direction position of a lens to be easily adjusted, and has resistance to impact, and an imaging apparatus.SOLUTION: The lens barrel according to the present invention comprises: a lens holding frame 30 that holds a lens, and has a first hole 31 provided in an outer circumference; a holding frame fixing cylinder 13 that is arranged in the outer circumference of the lens holding frame 30, and has a first opening part 110 provided in a circumferential face; position adjustment member 120 and 130 that are provided with second holes 132, and are mounted to the first opening part 110 while positioned in an optical axis direction; and a fixing member 140 that is inserted into the first hole 31 through the second hole 132 of the position adjustment members 120 and 130, and thereby define a position in the optical axis direction of the lens holding frame 30. The second hole 132 is provided so as to be eccentric from the optical axis-direction center of the first opening part 110 when the position adjustment members 120 and 130 are mounted to the first opening part 110.SELECTED DRAWING: Figure 3 【課題】レンズの光軸方向の位置調整を容易に行うことができると共に衝撃に対しても強いレンズ鏡筒および撮像装置を提供する。【解決手段】本発明のレンズ鏡筒は、レンズを保持するとともに、外周に第１の孔３１が設けられたレンズ保持枠３０と、レンズ保持枠３０の外周に配置され、周面に第１開口部１１０が設けられた保持枠固定筒１３と、第２の孔１３２が設けられ、第１開口部１１０に対して光軸方向に位置決めされて装着される位置調整部材１２０，１３０と、位置調整部材１２０，１３０の第２の孔１３２を貫通して第１の孔３１に挿入されることにより、レンズ保持枠３０の光軸方向の位置を規定する固定部材１４０と、を備え、第２の孔１３２は、位置調整部材１２０，１３０が第１開口部１１０に装着された際に第１開口部１１０の光軸方向の中心から偏心するように設けられていること、を特徴とする。【選択図】図３
