Image shake correction unit, lens apparatus using the same, and image pickup apparatus

An image shake correction unit, comprising:

• a base member;
• a yoke;
• a lens holding member that holds a lens unit and is movable in a direction orthogonal to an optical axis of the lens unit;
• a driving unit configured to move the lens holding member in the direction orthogonal to the optical axis;
• a rotation suppression unit that is provided on a side opposite to a side of the base member relative to the lens holding member, and is configured to suppress rotation of the lens holding member around the optical axis;
• and
• a biasing member configured to bias the lens holding member toward the base member in a direction of the optical axis, wherein
• the driving unit and the rotation suppression unit are disposed such that at least a part of the driving unit and at least a part of the rotation suppression unit are located on a circumference of a circle that has a predetermined radius centering on the optical axis in a case where the image vibration correction unit is viewed from the direction of the optical axis,
• the biasing member has one end provided on the rotation suppression unit and the other end provided on the base member,
• the lens holding member is movable in a first direction and a second direction that are orthogonal to the optical axis, and
• the rotation suppression unit includes a first guide member and a second guide member, the first guide member allowing the lens holding member to move in the second direction and being provided on a side opposite to the side of the base member relative to the lens holding member, the second guide member allowing the lens holding member to move in the first direction and being provided on a side opposite to the side of the lens holding member relative to the first guide member.
