Abstract
There is provided a lens barrel with an vibration reduction unit, which allows a reduction in dimension of the lens barrel in the optical-axis direction in the accommodated state, and an imaging device including such lens barrel. The lens barrel includes first and second lens units, a drive part for driving one of the first and second lens units in the optical-axis direction with respect to a stationary part, the drive part driving the one of the first and second lens units to approach each other during shifting to an accommodated state, and an vibration reduction part for moving the other lens unit in a plane substantially orthogonal to the optical axis so that at least part of a position of the other lens unit in the optical-axis direction coincides with a position of the drive part in the accommodated state.
