A blur correcting device comprises: a blur correction optical system that corrects an image blur by moving along a direction substantially perpendicular to an optical axis; a locking member that locks the blur correction optical system when an image blur correction is not executed; and a lock drive device having an elongated external shape with a length thereof set along a direction in which a tangential line of a circle having a center thereof at the optical axis extends on a plane substantially perpendicular to the optical axis, which generates a drive force to drive the locking member.
