PROBLEM TO BE SOLVED: To provide an image shake correction device that includes a configuration allowing grease to be stably supplied to a ceramic ball supporting a movable frame member over a long period of time.SOLUTION: An image shake correction device comprises: a stationary frame member 22; a movable frame member 14 that holds an optical lens 14a or an image pick-up element; a support member 31 that movably supports the movable frame member with respect to the stationary frame member in an in-plane orthogonal to an optical axis O of the optical lens or along a light reception surface of the image pick-up element; and a drive unit 25 that drives the movable frame member to the stationary frame member. In the stationary frame member or the movable frame member, there are formed: a support member arrangement part 22b that rollably stores a support member, and restricts an amount of movement in the in-plane of the support member; and a small area space part 22g in which a lubrication member 40 is filled into an interior part formed so as to communicate with the support member arrangement part with a part of the support member dispose part cut off.SELECTED DRAWING: Figure 5 【課題】可動枠部材を支持するセラミックボールにグリスを長期間に亘って安定供給し得る構成を備えた像振れ補正装置を提供する。【解決手段】固定枠部材２２と、光学レンズ１４ａ又は撮像素子を保持する可動枠部材１４と、固定枠部材に対し可動枠部材を光学レンズの光軸Ｏに直交する平面内又は撮像素子の受光面に沿う平面内で移動可能に支持する支持部材３１と、固定枠部材に対し可動枠部材を駆動する駆動ユニット２５とを具備し、固定枠部材又は可動枠部材は、支持部材を転動自在に収納すると共に支持部材の平面内での移動量を制限する支持部材配設部２２ｂと、支持部材配設部の一部を切り欠いて支持部材配設部と連通するように形成され内部に潤滑部材４０が充填される小領域空間部２２ｇとが形成されてなる。【選択図】図５
