まず、ゴム体１２の中央部に配置されるリンク１４Ｂを用意し、図５（Ａ）に示すように、両端部が接合されず、開いた状態のリンク１４Ａ、１４Ｃを、リンク１４Ｂにリンクさせる。次に、図５（Ｂ）に示すように、第１連結部材１６をリンク１４Ａの開口部分から入れてリンクさせ、第２連結部材１８をリンク１４Ｃの開口部分から入れてリンクさせる。第１連結部材１６及び第２取付部材１８のＵ字両端部１６Ｂ、１８Ｂは、リンク１４Ｂの中央穴の径よりも大きいため、環状に接合された後にリンクさせることはできない。このように、リンク１４Ａ及びリンク１４Ｃを開いたままでリンクさせることにより、容易にリンクさせることができる。そして、図５（Ｃ）に示すように、リンク１４Ａ、１４Ｃの両端部を溶接接合して環状とする。その後、ゴム体１２を形成して、図１に示す連結具１０が完成する。   First, a link 14B arranged at the center of the rubber body 12 is prepared, and as shown in FIG. 5A, the links 14A and 14C in an opened state are linked to the link 14B without joining both ends. . Next, as shown in FIG. 5B, the first connecting member 16 is inserted and linked through the opening portion of the link 14A, and the second connecting member 18 is inserted and linked through the opening portion of the link 14C. Since the U-shaped end portions 16B and 18B of the first connecting member 16 and the second attachment member 18 are larger than the diameter of the central hole of the link 14B, they cannot be linked after being joined in an annular shape. In this way, the links can be easily linked by linking with the links 14A and 14C open. Then, as shown in FIG. 5C, both ends of the links 14A and 14C are welded to form an annular shape. Thereafter, the rubber body 12 is formed, and the connector 10 shown in FIG. 1 is completed.

本実施形態の連結具１０は、第１連結部材１６及び第２連結部材１８がＵ字状とされているので、構造物に固定された取付プレート２６ＢをＵ字両端部１６Ｂ、１８Ｂで挟み込み、第１ボルト１７、第２ボルト１９を差し込むことにより、取り付けることができる。したがって、１箇所の取付部分に１枚の取付プレートで取り付けることができ、２枚の取付プレートを用いる場合と比較して、低コストで取り付けることができる。また、取付プレート２６Ｂの面外方向の挙動に対して追従性が向上する。   In the connector 10 of this embodiment, since the first connecting member 16 and the second connecting member 18 are U-shaped, the mounting plate 26B fixed to the structure is sandwiched between the U-shaped end portions 16B and 18B, It can be attached by inserting the first bolt 17 and the second bolt 19. Therefore, it can attach to one attachment part with one attachment plate, and it can attach at low cost compared with the case where two attachment plates are used.
