Abstract
A lens barrel that prevents an oscillation phenomenon caused by vibrations occurring when a lens of an image blur correction mechanism shifts. A first cylinder is engaged in the cam cylinder and caused to move in a direction of an optical axis by rotation of a cam cylinder. A second cylinder supports a lens holding member, which moves in a direction different from a direction of an optical axis so as to correct for an image blur, and is engaged in the cam cylinder and caused to move in the direction of the optical axis by rotation of the cam cylinder. The second cylinder has a first vibration isolation pin that is engaged with the first cylinder movably in the direction of the optical axis.
