See). The advancing / retreating rod 1B in the illustrated example is formed by bending a round steel having a diameter of about 6 mm into a U shape to form the slot 1C, but a slot may be formed by cutting along the center of a long flat steel.

Fastening parts 5 such as bolts and nuts for fixing the horizontal support rod 1 and the identification display plate 2 are provided so as to be movable along the advancing / retreating rod 1B (see FIG. 6). In the fastening component 5 of the illustrated example, a bolt 5A with a head is projected from the rear side of the advancing / retreating rod 1B to the front side through the slot 1C, and the mounting hole 2A of the identification display plate 2 is fitted to the bolt 5A on the front side of the advancing / retreating rod 1B. The nut 5B is tightened. A washer 5C is interposed between the advancing / retreating rod 1B and the identification display plate 2, and is formed in a U-shaped cross section so as to engage with the upper and lower sides of the advancing / retreating rod 1B to act as a detent. When the fastening component 5 is fully tightened, the identification display plate 2 is fixed to the horizontal supporting rod 1 (advancing / retracting rod 1B), and at the same time, the fastening component 5 is also fixed to the horizontal supporting rod 1 (advancing / retreating rod 1B).

At the outer end of each advancing / retreating rod 1B, that is, at both ends of the horizontal supporting rod 1, there is provided a support metal fitting 7 for mounting and supporting the horizontal supporting rod 1 on the leg member 6 of the steel tower. As shown in FIGS. 3 and 7, the metal support 7 is formed by bending a metal plate into a horizontally long U-shape, and the horizontally long length is slightly larger than the thickness of the diagonal member 8 of the steel tower. The end portion of the advancing / retreating rod 1B is attached to the top surface 7A of the support metal fitting 7 with a bolt 9 and a nut 10 so as to be slightly rotatable. Reference numeral 11 denotes a member for making a U-shaped piece fixed to the end of the advancing / retreating rod 1B to close the open end of the slot 1C and to form a through hole for the bolt 9.

Both ends of the corresponding two sides of the support fitting 7 are bent outwardly in an L-shape to form a seat 7B against the side surface of the leg member 6. The tip of the inner seat of the pair of seats 7B is further bent in a U shape to form a clip 12 which is hooked to the edge of the leg member (generally angle steel) 6. Then, a tightening band 13 such as a stainless band that penetrates through the support fitting 7 and goes around the outside of the abutment seat 7B and the clip 12 is provided. A buckle 14 is attached to the band 13.
