PURPOSE: To provide a distribution board arranging device for storing an optical waveguide plug-in system in a distribution cabinet by making it possible to easily attach/detach the distribution board or the optical waveguide plug-in system arranged on the distribution board and approach the cabinet as closer as possible. CONSTITUTION: Two horizontal U-shape rails 3, 4 are vertically arranged and fixed so that the apertures of their longitudinal slits 3..., 4... are opposed to each other. The leg parts 3', 3" of the upper U-shape rail 3 are longer than the leg part 4', 4" of the lower U-shape rail 4 and the longitudinal direction edge of the distribution board 5 is received between the leg parts 3', 3" and 4', 4". The width (a) of the board 5 is larger than an inward interval (b) between the outermost opposed edges 30, 40 of the leg parts 3', 3", 4', 4" of the rails 3, 4 and smaller than the inward interval (c) between rail bottom parts 30', 40'. |
