Abstract
A collapsible lens barrel includes: an opening/closing unit (shutter unit) that includes an opening/closing portion (shutter blade) openable and closable along a plane orthogonal to an optical axis to control a light amount, and a maintaining portion (projection) that maintains an opened state of the opening/closing portion; an inner lens disposed closer to an object than the opening/closing unit is; an inner frame that holds the inner lens; an outer lens disposed closer to the object than the inner lens is; an outer frame that holds the outer lens; and a restriction portion that restricts operation of the maintaining portion by restriction applied from the outer frame to the maintaining portion via the inner frame to maintain the opened state of the opening/closing portion when the outer frame and the inner frame are collapsed.
