Abstract
A lens apparatus includes a drive unit to drive a second lens barrel in an optical axis direction, a connection member to connect the second lens barrel and the drive unit, a movement base to hold the drive unit and move the drive unit in the optical axis direction with respect to a first lens barrel, and a second urging member to urge the movement base against the first lens barrel in a direction orthogonal to a plane passing through first, second, and third support portions. The connection member moves in a direction intersecting with a line connecting the first and second support portions. A moment by an urging force of the second urging member about an axis connecting the first and second support portions is greater than a moment by an urging force of the first urging member about the axis connecting the first and second support portions.
