Abstract:
This land-lock gate is provided with: a door body (2) that is hoisted by being rotated about a hoisting axial center (20); and a floor plate (38) that is arranged adjacently to the hoisting axial center (20) side of the door body (2) in an un-hoisted state. A groove (7) is formed between the end surface (72) of the door body (2) and the end surface (73) of the floor plate (38). The land-lock gate is further provided with a filling material (8) filling the groove (7). The filling material (8) is fixed to the end surface (72) of the door body (2) and the end surface (73) of the floor plate (38) between which the groove (7) is formed. The filling material (8) has elasticity, and is raised higher than the lower one of the upper ends of the end surfaces (72, 73) when the groove 7 becomes narrower due to raising of the door body (2).
