To enable downsizing as well as facilitating manufacturing work.SOLUTION: An optical element drive device comprises: a movable part capable of holding an optical element and movable in the optical axis direction by the drive of a drive part; a base part having a bottom part located on one optical axial side by being spaced apart from the movable part and an upright part vertically installed on the bottom part so as to protrude to the other optical axial side from an extension part that extends to the radial outside from the movable part; an elastic member that supports the movable part so as to be movable in the optical axis direction; and a vibration damping member interposed between the movable part and the upright part, for damping the vibration of the movable part. A first end part of the elastic member that is fixed to the extension part and the upright part are arranged at positions that are shifted from each other in the circumferential direction.SELECTED DRAWING: Figure 5
【課題】製造作業が容易になると共に、小型化が可能であること。【解決手段】光学素子駆動装置は、光学素子を保持可能であり、駆動部の駆動により光軸方向に移動する可動部と、可動部から光軸方向の一方側に離間して配置された底部と、底部において可動部より径方向外側に延出する延出部から光軸方向の他方側に突出するよう立設された立設部と、を有する基部と、可動部を光軸方向に移動可能に支持する弾性部材と、可動部と立設部との間に介設され、可動部の振れを抑制する制振部材と、を備え、弾性部材において延出部に固定される第1端部と立設部とは、互いに周方向にずらした位置に配置される。【選択図】図5
