Abstract:
1. A lens barrel comprising: a lens group that is movable along a first optical axis; a cam barrel that moves said lens group; a first transmission mechanism that transmits a driving force of a driving source to the said cam barrel; a bending optical element that is movable along a second optical axis that intersects the first optical axis; an element driver that moves said bending optical element to a position where said bending optical element bends a light flux entered through said lens group in the direction of the second optical axis when said lens group and said cam barrel move in an extending direction along the first optical axis, and that moves said bending optical element to an escape position along the second optical axis to form a storage space for said cam barrel when said lens group and said cam barrel move in a retracting direction along the first optical axis; and a second transmission mechanism that transmits a driving force of a driving source to said element driver, wherein said second transmission mechanism is arranged within an arrangement area of said first transmission mechanism when viewing in the direction of the first optical axis.
