Abstract
An image shake correction device capable of reducing a sliding friction force occurring with movement of a movable member, thereby reducing load on a drive unit for driving the movable member and improving the positioning accuracy of the movable member. The movable member of the correction device is supported to be movable in a yaw direction and supported to be pivotable in a pitch direction, and a ball is held between the movable member and a guide groove formed in a stationary member and extending in the yaw direction. When the movable member moves in the yaw direction, the ball rolls along the guide groove. When the movable member pivots in the pitch direction, a contact point where the movable member contacts with the ball functions as a pivotal fulcrum for the movable member.
