EXPANSION JOINT AND DRAIN PIPE STRUCTURE
To expand a downstream side diameter while reducing the number of components in a drainpipe structure.SOLUTION: There is provided an expansion joint 25A used in a drainpipe structure 1A, which comprises: a first connection port 26 connected upstream in the drainpipe structure 1A; a second connection port 27 connected downstream in the drainpipe structure 1A and having a larger diameter than the first connection port 26; and a curved pipe section 28 connecting the first connection port 26 and second connection port 27 and expanding in diameter from the first connection port 26 toward the second connection port 27.SELECTED DRAWING: Figure 1
【課題】排水管構造において、部品点数を抑えつつ下流側の拡径をする。【解決手段】排水管構造１Ａに用いられる拡径継手２５Ａであって、排水管構造１Ａにおける上流側に接続される第１接続口２６と、排水管構造１Ａにおける下流側に接続され、第１接続口２６よりも大径の第２接続口２７と、第１接続口２６と第２接続口２７とを接続し、第１接続口２６から第２接続口２７に向かうに従い拡径する曲管部２８と、を備える。【選択図】図１
