In a valve opening/closing device that transmits the driving force of an electric motor to an output shaft connected to a valve via a reduction gear, a spring is engaged with one end shaft of the reduction gear. The spring is wound up by the driving force of the electric motor, a rotation lock is provided at one end of the output shaft, and a shock absorber is provided on the rotation lock, so that when the electric power to the electric motor is cut off, the spring is wound up. 1. A valve opening/closing device having an emergency shutoff operation, characterized in that an output shaft is driven by an elastic driving force of the valve, and a sudden full closing operation is prevented by a shock absorber provided in a lock portion. 2. In a valve opening/closing device that transmits the driving force of an electric motor to an output shaft connected to a valve via a reduction gear, a spring is engaged with one end shaft of the reduction gear, and the driving force of the electric motor is used to drive the spring. Furthermore, a braking device is provided on one end shaft of the reducer in which the impeller rotates in sealed oil, and when the electric current to the motor is cut off, an output is generated by the elastic driving force of the spring. A valve opening/closing device having an emergency shutoff operation, characterized in that a shaft is driven and a braking device using an impeller prevents sudden full closing operation.
