<p>PROBLEM TO BE SOLVED: To improve shock resistance in a state in which an optical member for correcting an image shake is retreated from onto an optical axis.SOLUTION: An image shake correction device includes: a third group lens 2 correcting an image shake; a third group holder 3 holding the third group lens 2; a third group frame 8 supporting the third group lens 2 between a photographic position and a retreat position so that the third group lens 2 is rotatable in a R direction, and correcting an image shake of a subject image formed on an imaging element 30 through a photographic optical system including the third group lens 2 at the photographic position by moving in a P direction and a Q direction in plane orthogonal to an optical axis of the third group holder 3; a second group lens 25 arranged adjacent to the third group lens 2; and a photographic-time abutment member 17 arranged on a second group lens 25-side of the third group holder 3 when the third group lens 2 is at the photographic position, and moving in the P direction, Q direction, and R direction integrally with the third group lens 2, the photographic-time abutment member 17 including a photographic-time abutment portion 17 more protruding toward the second lens 25 than a second group lens 25-side surface of the third group lens 2 in an optical axis direction.</p> |
