Abstract
A lens unit includes a lens, a lens, a second O-ring disposed between the lens and the lens in an optical axis direction, and a second lens barrel that accommodates them. The second lens barrel includes an annular caulking portion which is brought into contact with an outer peripheral-edge portion of the lens from the object side and includes an object-side stepped portion on an inner peripheral surface. The lens is located between the caulking portion and the seating surface of the object-side stepped portion. The second O-ring is compressed in the optical axis direction at a position adjacent to an annular wall surface of the object-side stepped portion in a radial direction. The second O-ring exerts an urging force to urge the lens toward the object side and to urge the lens toward the image side.
