Beschreibung
Zusammenfassung:	A motor operated valve (100) includes a feed screw mechanism and a stopper mechanism. The feed screw mechanism includes a guiding part (242) including an external thread portion (244) on an outer surface thereof, and a guided part (326) that is a cylindrical member constituting a rotation shaft (326) of a rotor (320), and including an internal thread portion (328), which is engaged with the external thread portion (244), on an inner surface thereof. The stopper mechanism includes a stopper portion (327) provided on the guided part, and a stopping face (810) formed integrally with the guiding part. When a valve element (204) is driven by the motor (300) to move in a valve closing direction, the stopping face stops the stopper portion to restrict the movement of the rotor (320) in the valve closing direction.
