、締め付けボルト２０を完全に締め付けても良い。In addition, when fixing the C-shaped steel 13, the horizontal holding arm 25 is movably attached to the vertical mounting part 19 of the support member 16 with the tightening bolt 20 and nut 23 in advance, and the C-shaped steel is fixed to the horizontal support part 18 of the support member 16. 13, the horizontal holding arm 25 may be rotated as shown in FIG. 4, and the tightening bolt 20 may be completely tightened.
次に第５図に示す、実施例につき説明する。なお、この
実施例の説明に当って前記本発明の実施例と同一部分に
は同一の符号を付し、重複する説明を省略する。Next, the embodiment shown in FIG. 5 will be described. In the description of this embodiment, the same parts as those in the embodiment of the present invention are designated by the same reference numerals, and redundant explanation will be omitted.
第５図に示す実施例において前記本発明と実施例と主に
異なる点は、支持部材１６Ａと固定部材１７Ａである。The main difference between the embodiment shown in FIG. 5 and the embodiment described above is a support member 16A and a fixing member 17A.
すなわち、３０は支持部材１６Ａの垂直取付部１９Ａに
貫通状態に形成された締め付けボルト２ＯＡ用のメネジ
部である。この支持部材１６Ａにはナツト嵌合部が形成
されていない。したがって、固定部材１７Ａは水平保持
アーム２５Ａと締め付けボルト２０Ａとから成る。That is, 30 is a female threaded portion for the tightening bolt 2OA that is formed to penetrate through the vertical mounting portion 19A of the support member 16A. This support member 16A does not have a nut fitting portion formed therein. Therefore, the fixing member 17A consists of a horizontal holding arm 25A and a tightening bolt 20A.
