PROBLEM TO BE SOLVED: To obtain a pipe body, which is capable of feeding a fluid such as water or air, and which has superior designability to prevent the appearance of a water tank or garden part from being damaged.SOLUTION: In the pipe body which is configured by connecting a plurality of annular bodies in a chain shape, the annular bodies are formed to be hollow partially or entirely, and a through hole communicated to a hollow part is formed on each of surfaces confronted with each other of the adjacent annular bodies. The hollow parts of the adjacent annular bodies are communicated by a tubular body linking both through holes, and the tubular body is inserted freely removably to the through hole of one or both annular bodies between the adjacent annular bodies. Accordingly, a ring-shaped elastic body around the tubular body is held between the adjacent annular bodies.COPYRIGHT: (C)2013,JPO&INPIT【課題】 水や空気などの流動体を送ることができ、かつ、水槽や庭園の景観を損ねることがないデザイン性に優れた管体を得る。【解決手段】環状体を複数鎖状に連結してなる管体において、環状体の一部又は全部を中空状に形成し、隣接する環状体の互いに対抗する面にそれぞれ中空部へ通じる通孔を形成し、両通孔を繋ぐ筒体によって隣接する環状体の中空部を連通し、筒体を隣接する環状体における一方又は双方の環状体の通孔に対して抜き差し自在に通すことで該筒体を周回するリング状の弾性体を隣接する環状体によって挟む。【選択図】 図2
