    • A barrier device in which excessive relative displacements of barrier blades in an optical axis direction are restricted to ensure a normal opening and closing operation of the barrier blades. The barrier device has second, first, and third barrier blades disposed in this order in the optical axis direction. Restriction portions of the first barrier blades have through portions extending from shielding portions in the optical axis direction and extending through elongated holes of the second barrier blades, and have extension portions extending parallel to the shielding portions from image-plane-side ends of the through portions and positioned on the image plane side of the second barrier blades. During the entire stroke of opening and closing of the barrier blades, the extension portions can be engaged with the shielding portions, whereby the second barrier blades are restricted from moving away from the first barrier blades.

    • The lens apparatus includes a first barrel member, a second barrel member, a first rolling bearing and a second rolling bearing. The second barrel member includes a cam for moving a lens unit in an optical axis direction, is disposed inside or outside the first barrel member and rotatable around an optical axis with respect to the first barrel member. The first rolling bearing prevents relative displacements of the first and second barrel members in the optical axis direction and in a radial direction. The first rolling bearing is rotatable between the first and second barrel members. The second rolling bearing prevents the relative displacement of the first and second barrel members in the radial direction. The second rolling bearing is rotatable between the first and second barrel members. The first and second rolling bearing are arranged at positions away from each other in the optical axis direction.
