Lens barrel and imaging device

An imaging device, comprising:

• a lens barrel including
• a first lens unit including a first lens element and a first lens support frame supporting the first lens element,
• a second lens unit including a second lens element and a second lens support frame supporting the second lens element, and being supported by the first lens unit to be movable in an optical axis direction of the first lens element with respect to the first lens unit, and
• a drive unit arranged to be used to drive the second lens unit with respect to the first lens unit, and fixed to the first lens unit, the drive unit including a support plate fixed to the first lens unit to face a center of the second lens element, and a face of the support plate extending substantially parallel to a center axis of the second lens element;
• and
• a camera body supporting the lens barrel,
• wherein, when viewed in the optical axis direction, the drive unit is fixed to the first lens unit so that a first profile line formed by the first lens unit and the drive unit is substantially circular.

A digital camera, comprising:

• a lens barrel including
• a first lens unit including a first lens element and a first lens support frame supporting the first lens element,
• a second lens unit including a second lens element and a second lens support frame supporting the second lens element, and being supported by the first lens unit to be movable in an optical axis direction of the first lens element with respect to the first lens unit, and
• a drive unit arranged to be used to drive the second lens unit with respect to the first lens unit, and fixed to the first lens unit, the drive unit including a support plate fixed to the first lens unit to face a center of the second lens element, and a face of the support plate extending substantially parallel to a center axis of the second lens element;
• and
• a camera body supporting the lens barrel,
• wherein, when viewed in the optical axis direction, the drive unit is fixed to the first lens unit so that a first profile line formed by the first lens unit and the drive unit is substantially circular.
