PROBLEM TO BE SOLVED: To provide a lens frame, equipped with a shielding member for space between two lens frames which is superior in sliding ability and relatively moving by physically reducing the probability of infiltration of dust and dirt, by narrowing the gap between the lens frames. SOLUTION: The lens frame is equipped with a main lens frame 5, a sub lens frame 3, provided internally in the frame 5 and moving in the optical axis direction, while holding an optical system, and the shielding member 1 stuck to the inner surface of the frame 5, provided to slide in contact with the outer peripheral surface 4 of the frame 3 and shielding the gap between the frames 5 and 3. The member 1 is constituted of an elastic foaming material, where a diamond-like carbon film is formed at least at its part sliding in contact with the outer peripheral surface of the frame 3.
