<P>PROBLEM TO BE SOLVED: To provide a shake correction device that is small in size and low in cost and that reduces rotation of a shift member within a plane orthogonal to an optical axis. <P>SOLUTION: A shake correction device comprises: the shift member holding a lens; a first drive part configured to move the shift member with respect to a body part in a first direction within a plane orthogonal to the optical axis; and a second drive part configured to the shift member in a second direction different from the first direction. The first drive part is composed by arranging a first magnet, a first coil, and a first yoke and the second drive part is composed by arranging a second magnet, a second coil, and a second yoke, in that order in the direction of the optical axis. The first yoke has a first projection part projecting in the direction of the optical axis and toward the first magnet. The second yoke has a second projection part projecting in the direction of the optical axis and toward the second magnet. As viewed in the direction of the optical axis, the width of the first projection part in a first direction that is far from the second yoke is greater than that close to the second yoke, and the width of the second projection part in the second direction far from the first yoke is greater than that close to the first yoke. <P>COPYRIGHT: (C)2013,JPO&INPIT |
