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) mounted vertically on a body (200) and including an external thread portion (244), and a guided part (326) made of a cylindrical member constituting a rotation shaft (326) of a rotor (320), and including an internal thread portion (328) to be engaged with the external thread portion. The stopper mechanism includes a projection (250) formed on the outer surface of the guiding part, and a stopper member (500) removably mounted on the guided part, and including a stopper (506) sticking out radially inward of the inner surface of the guided part. When a valve element (204) is driven by a motor (300) to move in a valve opening direction, the stopper is stopped by the projection in a rotor rotating direction, so that the translational movement of the rotor is restricted.
