<p><P>PROBLEM TO BE SOLVED: To provide a lens barrel that has a lens moved in both a variable power operation and a focusing operation. <P>SOLUTION: Lens barrel comprises: a holding member that moves with respect to a reference member while holding an optical system; a guide shaft that guides the moving direction of the holding member while supported by the reference member; and a linking member that generates driving force for moving the holding member, while rotating around the optical axis of the optical system. The linking member has a first engagement part that transmits driving force from the linking member to the holding member and a second engagement part that, when external force different from driving force is applied to the holding member, transmits part of the external force from the holding member to the linking member. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
