PROBLEM TO BE SOLVED: To reduce manufacture costs by supporting a barrier blade with a simple constitution in a lens barrel equipped with a barrier device. SOLUTION: The barrier blade 55 is put between a front side holding body 56 and a rear side holding body 57 and held to be opened/closed. By engaging a hook part 65 projecting from the front side holding body 56 with a hook receiving part provided to be recessed on the rear side holding body 57, the front side holding body 56 and the rear side holding body 57 are fixed to each other. A situation that the hook part 65 is warped to an outer periphery side and a projection part comes off from the hook receiving part is prevented by a 1st group lens frame 21. Furthermore, by fitting a decorative barrel in the 1st group lens frame 21 from an edge side, the front side holding body 56 and the rear side holding body 57 are surely attached to each other.
