Beschreibung
Zusammenfassung:	A motor operated valve (100) includes a feed screw mechanism and a stopper mechanism. The stopper mechanism includes: a first stopper mechanism including a first stopper portion (820) on the guided part, and a first stopping face (830) that is formed integrally with the guiding part and that stops the first stopper portion to restrict the movement of the rotor in the valve opening direction; and a second stopper mechanism including a second stopper portion (800) on the guided part, and a second stopping face (810) that is formed integrally with the guiding part and that stops the second stopper portion to restrict the movement of the rotor in the valve closing direction. The first stopping face and the second stopping face are located between the screwed portion of the feed screw mechanism and the valve section.
