<p><P>PROBLEM TO BE SOLVED: To minimize a dominant region by arm metals and to hold down a decline in beauty to the minimum. <P>SOLUTION: A structure for joint use comprises: arm metal members 10 and 20 which are installed on an electric pole 5 at different heights in such a manner as to protrude from the electric pole 5; and a linking member 30 which has a predetermined length, with one end in the length direction joined to a predetermined site of the arm metal member 10 and the other end joined to a predetermined site of the arm metal member 20, and which allows electric cables to be attached to the side thereof. At the ends of the arm metal members 10 and 20, extension arm metal attachment portions 12 and 22 are installed outside the predetermined sites to which the linking member 30 are joined. Due to this structure, extension arm metals can be attached easily, resulting in easily changing the length of the arm metals. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
