PROBLEM TO BE SOLVED: To provide a sluice gate mounting plate facilitating attachment/detachment to prevent trouble caused by freezing or the like of a sluice gate device installed in a waterway, particularly of an automatic sluice gate. SOLUTION: Fixing and a countermeasure against a water leakage can be attained by a mechanism for pressing a pressure plate to a waterway face by a screw mechanism or a clamp mechanism in the waterway when mounting the sluice gate device to the waterway, and a reliable countermeasure against the water leakage can be further attained with packing 12 and a sealing material. The sluice gate device 4 can be attached/detached by these mechanisms, and trouble such as freezing can be prevented in advance. COPYRIGHT: (C)2008,JPO&INPIT
