Abstract

Provided is a lens barrel including: a guide shaft in an axial form supported by a reference member; a holding member holding an optical system, and movable in an axial direction of the guide shaft with respect to the reference member; and an interlocking member including an engaging section engaging with the holding member, the interlocking member moving in the axial direction while rotating around an optical axis of the optical system, and moving along the guide shaft without rotating the holding member. The lens barrel may include a driving cylinder including a cam groove engaging with the interlocking member, where when rotated around the optical axis, the driving cylinder drives the interlocking member by means of the cam groove, to cause the interlocking member to move linearly in the direction of the guide shaft.
