Summary:PROBLEM TO BE SOLVED: To provide a compact and shock resistant lens barrel, and an image capturing device having the same.SOLUTION: A lens barrel is divided by a plane that is perpendicular to a center line NL connecting the center of a drive cam pin 170 and an optical axis AX and contains the optical axis into a near side portion NSD defined as a side with the drive cam pin 170 and a far side portion FSD defined as a side opposite the near side portion NSD. When an impact force displaces a third holding frame 115 in a direction of an arrow B, at least either of the third holding frame 115 and a fourth holding frame 117 is the first one to come into contact with a part to be contacted first in the near side portion NSD.SELECTED DRAWING: Figure 9 【課題】小型でありながら、耐衝撃性を確保したレンズ鏡筒及びそれを用いた撮像装置を提供する。【解決手段】駆動用カムピン１７０の中心から光軸ＡＸに下ろした中心線ＮＬに直交し且つ光軸ＡＸを通る平面で、レンズ鏡筒を駆動用カムピン１７０が存在する側を近側部ＮＳＤとし、近側部ＮＳＤと反対の側を遠側部ＦＳＤとする。衝撃力を受けて第３保持枠１１５が矢印Ｂ方向に変位した場合、第３保持枠１１５と第４保持枠１１７とは、そのうち少なくとも一方が近側部ＮＳＤにおける最先当接部に、最初に衝接する。【選択図】図９
