Lens barrel

A camera shake-correction device comprising:

• a movable member that holds a camera shake-correction lens or an image sensor;
• a base member that supports the movable member such that the movable member is movable in a plane orthogonal to an optical axis;
• a plurality of rolling bodies that are provided between the movable member and the base member;
• an urging member that urges the base member toward the movable member;
• a first motor that drives the movable member in a first direction in the plane orthogonal to the optical axis;
• a second motor that drives the movable member in a second direction orthogonal to the first direction in the plane orthogonal to the optical axis;
• a first shaft that is provided at the movable member and that is disposed to be orthogonal to the optical axis;
• a swinging member of which a proximal end portion is swingably supported by the first shaft;
• a second shaft that is provided at a distal end portion of the swinging member and that is disposed to be parallel with the first shaft;
• a sliding portion that is provided at the movable member and that slides along the second shaft;
• and
• a restricting member that is provided at the base member and that restricts movement of the movable member in a direction away from the base member, wherein:
• the sliding portion includes a groove portion that is open in a direction in which the movable member is separated from the base member;
• and
• the second shaft is fitted to the groove portion and is slidably supported.
