To provide a water cut-off device or the like having good water cut-off performance even when there is unevenness such as a groove on the ground.SOLUTION: A rising portion 5 rises on a rear end side of an installation portion 3. On a lower surface on a front end side of the installation portion 3, a lower surface water cut-off member 23a is disposed on the front end side of the installation portion 3, and a lower surface water cut-off member 23 is disposed on a rear side of the lower surface water cut-off member 23a. The lower surface water cut-off member 23a has convex portions each having a convex shape that becomes thinner toward a distal end in a cross section. The convex portions are continued in a continuous manner in a longitudinal direction of the lower surface water cut-off member 23a. Here, a direction in which the convex portions are continued is referred to as a ridge direction of the convex shape. The ridge direction of the convex shape of the lower surface water cut-off member 13a disposed on a front end side of a water cut-off device 1b is substantially parallel to a side on the front end side of the installation portion 3.SELECTED DRAWING: Figure 14 【課題】 地面に溝などの凹凸がある場合であっても止水性能が良好な止水装置等を得る。【解決手段】 起立部５は設置部３の後端側で起立する。設置部３の前端側の下面において、設置部３の前端側に下面止水部材２３ａが配置され、下面止水部材２３ａの後方に下面止水部材２３が配置される。下面止水部材２３ａは、断面において、先端に行くにつれて細くなる凸形状の凸部を有する。凸部は、下面止水部材２３ａの長手方向に対しれ連続する。ここで、この凸部の連続する方向を、凸形状の尾根方向と称する。止水装置１ｂの前端側に配置される下面止水部材１３ａの凸形状の尾根方向は、設置部３の前端側の辺に略平行である。【選択図】図１４
