description	PROBLEM TO BE SOLVED: To provide an electric opening/closing device of a sluice gate, which electrically opens/closes a sluice gate door to be opened/closed by manual operation usually to make a worker free from heavy labor for opening/closing the sluice gate door speedily and safely. SOLUTION: A manually operated handle of the sluice gate door is removed, the electric opening/closing device 20 of charging type of the sluice gate having an output shaft 21 to be engaged with a driving shaft 13 is engaged therewith, and they are integrally fixed. This electric opening/closing device 20 of the sluice gate uses a motor driven by a lithium ion battery 31 of charging type as a driving source to open and close the sluice gate electrically through a reduction gear 30 mounted on the driving shaft 13. When the driving shaft 13 causes abnormal vibration, a rotary start knob held and magnetized by a trigger switch and a magnet is separated through the vibration to stop in an emergency.
