PROBLEM TO BE SOLVED: To facilitate assembling and adjustment of a guide shaft in a lens barrel. SOLUTION: This lens barrel comprises a plurality of guide shafts for guiding the moving direction of a lens holding member for holding a lens, a fixed cylinder for supporting one end of the plurality of guide shafts, and a supporting member that supports the other end of the plurality of guide shafts and is attached to the fixed cylinder. The length dimension along the moving direction of the supporting member may be smaller than that of the fixed cylinder. In a state where the guide shafts are supported by the fixed cylinder, the guide shafts may be arranged on the inner peripheral side of the fixed cylinder. COPYRIGHT: (C)2010,JPO&INPIT
