Abstract:
A lens barrel, comprising:first and second lens frames, adapted to be able to make a relative displacement therebetween and adapted so that an inner peripheral portion of said first lens frame overlaps with an outer peripheral portion of the second lens frame even when the first and second lens frames are fully extended in a used state;a light shielding portion, provided at one end portion of said first lens frame and which overlaps said second lens frame, for blocking light, which is incident on said one end portion in the used state, from entering between said first and second lens frames; anda pressure-contact light shield member that is provided in a recess in an end portion of the inner periphery of said first lens frame, which recess is located further inwardly from said one end portion of said first lens frame than said light shielding portion provided at the one end portion thereof and that is adapted to be elastically deformed by being pressure-contacted to an outer peripheral portion of said second lens frame, thereby blocking light transmitted by said light shielding portion provided at the one end portion of said first lens frame.
