<p><P>PROBLEM TO BE SOLVED: To prevent the occurrence of looseness of an arm mounting band in a strong wind. <P>SOLUTION: A concrete pole 101 has an upper pole part 110 and a lower pole part 120. The lower pole part 120 is tapered to be thicker toward the lower end from the upper end. The upper pole part 110 is not tapered. When a band-like contact fitting (the arm mounting band) 211 is fixed to the upper pole part 110, a subtle space like the case of using a conventional tapered concrete pole is not formed between the upper part of the contact fitting 211 and the outer surface of the upper pole part 110. The upper pole part 110 and the lower pole part 120 are independently formed, and the lower end of the upper pole part 110 and the upper end of the lower pole part 120 are joined using flange parts 111, 121 to facilitate manufacture. A projection 114 for preventing the downward slip of the contact fitting 211 is formed at the upper pole part 110, corresponding to the fixed position of the band-like contact fitting 211. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
