PROBLEM TO BE SOLVED: To facilitate the mounting work of a branching switch, and improve the appearance without exposing a lead-in cable by mounting the rear of a branching switch to the periphery of a pole. SOLUTION: An opening 17 is made at the periphery of a hollow pole 1, and the rear of a branching switch 3 is mounted on the brim of the opening 17. A lead-in cable 24, which is introduced into the pole 1 and whose tip is connected to the rear of the branching switch 3, is branched within the branching switch 3, and the branching cable 26 is led out of the branching switch 3 through a switch part. Since the rear of the branching switch 3 is mounted at the brim of the opening 17 made at the peripheral wall of the upper part of the pole 1, conventional hanging metal fittings, etc., become needles, and the mounting work can be facilitated, and also the appearance can be improved. |
