。 A bevel gear and a manual handle that are electrically driven through a spur gear reduction part are rotatably supported on a common shaft, and the bevel gear and the manual handle slide on the common shaft, and one bevel gear or the other manual handle is rotatably supported. A clutch plate is provided that connects with the handle and drives a common shaft.
The clutch plate is biased to one side by a spring to be permanently connected to the bevel gear, and a switching lever is provided to press the clutch plate connected to the bevel gear to the other side to connect it to the manual handle. The automatic return system is characterized in that a pressing cam for automatic return is pivotally supported on the clutch plate pressing section of the switching lever, and the input shaft of the worm reduction section, which is connected to the opening/closing shaft of the valve, is slidably connected to a common shaft. Valve drive actuator with built-in mechanism.
