Claims

[Claims for Utility Model Registration] A control valve having a valve body that can open and close a valve seat formed in a passage passing through the valve, and a valve shaft that guides the valve body so as to be movable in the axial direction; An electric flow control valve comprising a motor that is provided with a moving output shaft and that is capable of driving the valve shaft of the control valve with the output shaft to open and close the control valve. a first output shaft that moves linearly by a conversion means that converts rotational motion into linear motion; and a first output shaft that moves linearly in conjunction with the first output shaft and is capable of driving the valve shaft relative to the control valve. a second output shaft provided between the first output shaft and the second output shaft, the relative position of which is adjusted in the axial direction so that the second output shaft protrudes; An electric flow rate control valve comprising: an adjusting means whose length can be adjusted, and the opening degree of the control valve can be finely adjusted by adjusting the protruding length of the second output shaft.
