Abstract
A blur correcting device comprises: a blur correction optical system that corrects an image blur by moving along a direction extending substantially perpendicular to an optical axis; a movable member that includes the blur correction optical system and moves together with the blur correction optical system; a blur correction drive unit that drives the movable member; and a pressure member that applies pressure to the movable member in a direction extending substantially along the optical axis of the blur correction optical system, and switches between a state in which the pressure is applied to the movable member and a state in which no pressure is applied to the movable member by moving within a plane substantially perpendicular to the optical axis.
