Lens barrel

The lens barrel according to claim 2, further comprising

• a board which is integrally provided on a base end of the stationary frame;
• a retreating lens holding frame which is included in at least one of the plurality of lens holding frames, and which turns and retracts the held lens group on an outer side from an inner diameter of the movable frame in the retracted state;
• a main shaft which is provided substantially in parallel to the optical axis integrally with the board as a rotation center for turning and retracting the retreating lens holding frame on a plane which is perpendicular to the optical axis;
• and
• an auxiliary shaft which is arranged substantially in parallel to the main shaft and stands on the board, the auxiliary shaft positioning the retreating lens holding frame in a rotation direction at a position where a center of the lens group held by the retreating lens holding frame and an optical axis of the movable frame match with each other,
• wherein the auxiliary shaft is inserted through the through hole in the retracted state and the through hole is located at a position where the auxiliary shaft is separated in the shooting state, and the light shielding piece is arranged in the light shielding state when the auxiliary shaft is separated from the through hole in the shooting state.

A lens barrel comprising

• a stationary frame;
• a movable frame which includes a plurality of lens holding frames for respectively holding a plurality of lens groups, and which is supported by the stationary frame such that the movable frame is movable between a retracted state where at least one or more of the plurality of lens groups are retracted into the stationary frame and a shooting state where the lens group is moved toward an object of shooting;
• a lens holding frame driving apparatus which is provided on the stationary frame to drive the movable frame including the lens holding frame;
• a through hole formed in at least one of the plurality of lens holding frames;
• and
• a light shielding member made of polyester-based polyurethane foam which is pasted on at least a portion of an inner peripheral wall of the through hole to close the through hole.
