The cross section of the state attached to the plane part 81 of the attachment 8 is shown.

ここで、本実施形態2では、図16から明らかなように、ビョウ81e1〜81h1の軸部81e2〜81h2の長さは、銘板10の厚さd1と、アタッチメント8の平面部81の厚さd2と、スペーサ9の厚さd3との合計より短くなるように、スペーサ9の厚さd3を確保している。   Here, in Embodiment 2, as is apparent from FIG. 16, the lengths of the shaft portions 81e2 to 81h2 of the leopards 81e1 to 81h1 are the thickness d1 of the nameplate 10 and the thickness d2 of the flat surface portion 81 of the attachment 8. Further, the thickness d3 of the spacer 9 is ensured so as to be shorter than the total of the thickness d3 of the spacer 9.

これにより、本実施形態2では、銘板10を取付けるビョウ81e1〜81h1の軸部81e2〜81h2の先端部が、アンテナ側金具33に当たることを防止して、アンテナ側金具33と干渉することなく、またビョウ81e1〜81h1の軸部81e2〜81h2がアタッチメント8の平面部81の厚さd2とスペーサ9の厚さd3との合計より長いことによりビョウ81e1〜81h1の頭が浮くこと等を防止して、銘板10を取付けることができる。   Thereby, in this Embodiment 2, it prevents that the front-end | tip part of shaft part 81e2-81h2 of Byo 81e1-81h1 which attaches nameplate 10 contacts antenna side metal fitting 33, and does not interfere with antenna side metal fitting 33, and The shaft portions 81e2 to 81h2 of the leopards 81e1 to 81h1 are longer than the sum of the thickness d2 of the flat surface portion 81 of the attachment 8 and the thickness d3 of the spacer 9, thereby preventing the heads of the leopards 81e1 to 81h1 from floating, A nameplate 10 can be attached.

従って、本実施形態2のアンテナ用チルト金具によれば、上記実施形態1のアンテナ用チルト金具と同様に、上下2箇所でアンテナ3を支持する場合でも、同一の基部金具1と調整部金具2からなるアンテナ用チルト金具を上側金具Uとしても、下側金具Dとしても上下逆にせずにそのまま使用することができ、部品点数が増えず、かつ、所定角度毎の仰角を簡単かつ精度良く設定することができると共に、基部金具1および調整部金具2を小型化して、軽量化することができる。   Therefore, according to the antenna tilt bracket of the second embodiment, similarly to the antenna tilt bracket of the first embodiment, the same base bracket 1 and adjustment bracket 2 can be used even when the antenna 3 is supported at two upper and lower positions. The antenna tilt bracket can be used as the upper bracket U or the lower bracket D without being turned upside down, the number of parts does not increase, and the elevation angle for each predetermined angle can be set easily and accurately. In addition, the base metal fitting 1 and the adjustment metal fitting 2 can be reduced in size and weight.

特に、本実施形態2のアンテナ用チルト金具では、アタッチメント8とアンテナ側金具33との間にスペーサ9を設け、ビョウ81e1〜81h1の軸部81e2〜81h2の長さが、銘板10の厚さd1と、アタッチメント8の平面部81の厚さd2と、スペーサ9の厚さd3との合計より短くなるように、スペーサ9の厚さd3を確保したので、銘板10を取付けるビョウ81e1〜81h1の軸部81e2〜81h2の先端部がアンテナ側金具33に当たることを防止することができる。   Particularly, in the antenna tilt bracket of the second embodiment, the spacer 9 is provided between the attachment 8 and the antenna side bracket 33, and the length of the shaft portions 81e2 to 81h2 of the bows 81e1 to 81h1 is the thickness d1 of the nameplate 10. Since the thickness d3 of the spacer 9 is secured so as to be shorter than the sum of the thickness d2 of the flat surface portion 81 of the attachment 8 and the thickness d3 of the spacer 9, the shaft of the views 81e1 to 81h1 to which the nameplate 10 is attached It can prevent that the front-end | tip part of part 81e2-81h2 hits the antenna side metal fitting 33. FIG.

なお、本実施形態2では、軸部81e2〜81h2にネジ山が形成されていないビョウ81e1〜81h1により銘板10を取付けるように説明したが、本発明では、これに限られず、軸部81e2〜81h2にネジ山が形成されたビス等により銘板10を取付けるようにしても勿論よい。   In the second embodiment, the nameplate 10 is described as being attached by the bellows 81e1 to 81h1 in which the threads are not formed on the shaft portions 81e2 to 81h2. However, the present invention is not limited to this, and the shaft portions 81e2 to 81h2 Of course, the nameplate 10 may be attached by screws or the like in which a screw thread is formed.
