(EN) PROBLEM TO BE SOLVED: To provide an optical unit with swing correcting function in which resonance is not generated even when applying elasticity to a swing fulcrum supporting a movable body.
SOLUTION: In configuring a swing fulcrum 180 which supports a movable body 3 in an optical unit 100 with swing correcting function, a first plate part 181 in which a hole 181a is formed, an elastic member 185 made of an elastomer arranged so as to be superposed on the first plate part 181 on a rear side in the optical axis direction, and a second plate part 182 arranged so as to be superposed on the elastic member 185 on a rear side in the optical axis direction are provided in a part facing a rear end part of the movable body 3 in a solid body 200. Among the elastic member 185, a convex part 185g protruding from the hole 181a toward the movable body 3 configures the swing fulcrum 180.

【課題】可動体を支持する揺動支点に弾性を付与した場合でも共振が発生しない振れ補正機能付き光学ユニットを提供すること。
【解決手段】振れ補正機能付きの光学ユニット１００において、可動体３を支持する揺動支点１８０を構成するにあたって、固定体２００において、可動体３の後端部分に対向する部分に、穴１８１ａが形成された第１板部１８１と、第１板部１８１に対して光軸方向後側で重ねて配置されたエラストマー製の弾性部材１８５と、弾性部材１８５に対して光軸方向後側で重ねて配置された第２板部１８２とを設ける。弾性部材１８５のうち、穴１８１ａから可動体３に向けて突出した凸状部分１８５ｇが揺動支点１８０を構成する。
