To provide a water gate opening/closing device capable of reducing the size of a speed reduction mechanism including an electric motor, improving the arrangement balance, suppressing an increase in size, and being inexpensive.SOLUTION: A water gate opening/closing device 1 comprises an electric motor 11 arranged on a speed reducer case 10 for raising and lowering a door body, and a worm gear 21 which is provided in the speed reducer case 10 and receives rotation from the electric motor 11 for raising and lowering the door body. The worm gear 21 has a self-locking function. As a result, in the water gate opening/closing device 1, the parts of the reduction mechanism (speed reducer case 10) including the electric motor 11 can be made compact, the arrangement balance can be improved, the size increase can be suppressed, and the cost can be reduced.SELECTED DRAWING: Figure 2
【課題】電動機を含む減速機構の部位をコンパクト化し、且つその配置バランスを改善することができ、大型化を抑制でき、安価な水門開閉装置を提供する。【解決手段】水門開閉装置１は、減速機ケース１０上に配置され、扉体を昇降させる電動機１１と、減速機ケース１０内に設けられ、電動機１１からの回転が伝達されて、前記扉体を昇降させるウォームギヤ２１と、を備え、該ウォームギヤ２１は、セルフロック機能を有する。これにより、水門開閉装置１では、電動機１１を含む減速機構（減速機ケース１０）の部位をコンパクト化し、且つその配置バランスを改善することができ、大型化を抑制でき、安価にすることができる。【選択図】図２
