<P>PROBLEM TO BE SOLVED: To provide a lens barrel having a small number of components and capable of reducing an influence of blur correcting means on the gravity direction at a small power consumption. <P>SOLUTION: This lens barrel includes: blur correcting means moving in an optical-axis orthogonal direction with respect to a fixed portion for correcting blur of an image; guide means movably supported in a first direction orthogonal to the optical axis with respect to the fixed portion and movably supporting the blur correcting means in a second direction; a lock ring rotationally supported to the fixed part and restricting a locking state and an unlocking state of the blur correcting means, and the moving range of the blur correcting means; and a magnet and a coil for actuating the lock ring. The guide means includes a member for generating a magnetic attraction between itself and the magnet, a part thereof opposing the magnet, when the optical apparatus is in a normal position, is energized inversely to the gravity direction by the magnetic attraction so as to energize the blur correcting means inversely to the gravity direction. <P>COPYRIGHT: (C)2012,JPO&INPIT |
