Abstract: An image shake correction device includes a movement restrictor that restricts movement of a movable member in directions X, Y, θ, and Z. The movement restrictor includes a movement prevention member that is fixed to a base of a support member and prevents the movable member from moving in the direction Z while sandwiching the movable member in cooperation with the support member, a hole portion formed in the support member, and an insertion member that is formed in the movable member and is inserted into the hole portion. A wide width portion of the insertion member has a size that overlaps with the base of the support member even in a state in which an abutting portion of the insertion member is positioned in any position in the hole portion.
