Title
(EN) OPTICAL UNIT WITH SHAKE CORRECTING FUNCTION
(JA) 振れ補正機能付き光学ユニット
Abstract
(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。
