Zusammenfassung:To make an underwater attaching/detaching work of a door body easy.SOLUTION: A lifting gate 1 comprises a door body 10 and a bearing 2. The bearing 2 is formed as a split structure including a base 3 and a rear side attachment 5 which is disposed at a second water area B side with respect to a shaft center X and is attached to one end portion of the base 3 in a circumferential direction. A sliding face 21 is formed across the base 3 and the rear side attachment 5. A base face 21a that is a part formed in the base 3 in the sliding face 21 is positioned below a horizontal plane HP including the shaft center X and is formed in an arc shape with a central angle equal to or smaller than 180 degrees around the shaft center X.SELECTED DRAWING: Figure 4 【課題】水中での扉体の着脱作業を容易にする。【解決手段】起伏ゲート１は、扉体１０と軸受２とを備えている。軸受２は、ベース３と、軸心Ｘに対して第２水域Ｂの側に配置され、ベース３のうち周方向の一端部に取り付けられる後側アタッチメント５とを含む分割構造に形成されている。摺動面２１は、ベース３及び後側アタッチメント５に亘って形成されている。摺動面２１のうちベース３に形成された部分であるベース面２１ａは、軸心Ｘを含む水平面ＨＰよりも下方に位置し、且つ、軸心Ｘを中心に１８０度以下の中心角を有する円弧状に形成されている。【選択図】図４
