ABSTRACT:
A lens barrel includes a fixed barrel having an approximately cylindrical shape; a lens frame132disposed inside of the fixed barrel for holding the lens group; at least one shaft135A engaging in the lens frame132for guiding the lens frame132in a direction parallel to the optical axis of the lens group; and a guide shaft135B provided to a perimeter of the lens frame for regulating a rotation of the lens frame about the shaft. The lens frame132is disposed in the fixed barrel so that a center axis102of the fixed barrel and an optical axis101of the lens group do not coincide with each other, but are deflected in parallel, The shaft135A and the guide shaft135B are disposed so that a central angle θ1formed with respect to the center axis102of the fixed barrel is less than 180 degrees.
