Abstract: A lens barrel in which an air flow path that causes an external space and an internal space to communicate is formed includes an aperture unit disposed in the internal space and configured to rotate a plurality of vane members within a predetermined range to form a predetermined opening, an optical unit disposed in the internal space and located on an object side with respect to the aperture unit, and a through-hole formed in the aperture unit and communicating with the internal space. When at least one of the optical unit and the aperture unit moves in an optical axis direction, the lens barrel discharges, through the air flow path and the through-hole, air in the internal space and static electricity charged in the plurality of vane members included in the air in the internal space.

Abstract: A blur correction apparatus includes a first fixing member, a moveable member and a second fixing member. A coil for generating a magnetic flux is arranged on the first fixing member. The movable member includes (1) an optical element, (2) a first magnet facing the coil, and (3) a second magnet arranged along a line parallel with an optical axis of the optical element and facing the first magnet, such that the first magnet is arranged between the second magnet and the coil. The movable member can move in a direction perpendicular to the optical axis. The second fixing member includes a hall element that is arranged adjacent to the second magnet. The second magnet is arranged between the first magnet and the hall element. The coil, the first magnet, the second magnet and the hall element are sequentially disposed in a line parallel with the optical axis, in this order.
