PROBLEM TO BE SOLVED: To provide an artificial wood fence that prevents rusting of internal metallic members, even when gaps are formed between posts and a crossbar due to aging.SOLUTION: A first and second recesses 20 and 21 are formed on outer periphery of a post 11, a connecting bolt 37 is inserted into a hole 25 pierced through bottom surfaces 23 and 24 of the recesses 20 and 21, and bellows 41 and 42 are disposed inside the recesses 20 and 21. A front end A and a rear end B of a crossbar 12 are fitted into the recesses 20 and 21, respectively, for compressing the bellows 41 and 42, while a male screw 39a of the connecting bolt 37 is threaded through a female screw 35a of a cap 33, thus tightening and fixing a cylindrical body 40 attached on the connecting bolt 37 while compressing the cylindrical body against the bottom surface 23. Then, a fixing bolt 45 inside an insertion hole 43 on the side with the rear end B of the crossbar 12 is tightened and fixed.
【課題】経年経過して支柱と横木との間に隙間が生じても内部の金属部材を錆びさせることない擬木柵を提供すること。【解決手段】支柱１１の外周にそれぞれ第１及び第２の凹部２０，２１を形成し、両凹部２０，２１の底面２３，２４に開口する透孔２５に連結ボルト３７を挿通させ、凹部２０，２１内にベローズ４１、４２を配置する。それぞれの凹部２０，２１に横木１２の前端部Ａ及び後端部Ｂを嵌合させてベローズ４１，４２を圧縮するとともに、連結ボルト３７の雄ねじ３９ａをキャップ３３の雌ねじ３５ａに螺合させ、連結ボルト３７に装着させた筒体４０を底面２３に対して押圧状態となるように締めて固定する。次いで横木１２の後端部Ｂ側の挿通孔４３内の固定ボルト４５を締めて固定する。【選択図】図１
