Image shake correction device and imaging device

An image shake correction device comprising:

• a movable member;
• an imager that is fixed to the movable member;
• a support member that supports the movable member to be movable in a direction along a circumferential direction of a circle whose center is a center of a light receiving surface of the imager;
• and
• two movement restrictors that restrict a movement range of the movable member,
• wherein each of the two movement restrictors includes a recess portion or a through-hole formed in one of the movable member and the support member, and an insertion member formed in other one of the movable member and the support member and inserted into the recess portion or the through-hole,
• a shape of the recess portion or the through-hole as viewed in a direction perpendicular to the light receiving surface is a rectangle having two sides parallel to a longitudinal direction of the light receiving surface and two sides parallel to a short direction of the light receiving surface, and
• in a state in which the insertion member is present at a center of each of the two recess portions or through-holes, a line extending diagonally through each one of the two rectangles overlaps the center of the light receiving surface.
