ABSTRACT:
A lens barrel is provided with: first and second lens frames which are adapted to be able to make a relative displacement therebetween and are adapted so that an inner peripheral portion of one of the first and second lens frames overlaps with an outer peripheral portion of the other lens frame in a used state; a light shielding portion, which is provided at one end portion of the first lens frame, for blocking light which is incident from the end portion in the used state; and a pressure-contact light shield member that is provided at a place which is nearer to an other end portion of the first lens frame than the light shielding portion provided at the one end portion thereof and that is adapted to be elastically deformed by being pressure-contacted to the outer peripheral portion of the second lens frame, thereby blocking light transmitted by the light shielding portion provided at the one end portion of the first lens frame.
