摘要： A lens barrel has: a first barrel; an aperture unit held by the first barrel and having a variable aperture diameter; a second barrel at the subject side of the aperture unit and movable along the optical axis such that the position relative to the first barrel is variable; and a motor unit for moving the second barrel along the optical axis. The motor unit has a motor head portion generating a rotative force and a lead screw portion driven to rotate by the rotative force. The lead screw portion is arranged to bridge from the subject side to the imaging side of the aperture unit. The motor head portion is arranged at the imaging side of the aperture unit. An optical axis-side part of the motor head portion is located at the optical axis side of an outer circumferential portion of the aperture unit.
