To attain improvement of lubricating performance in a drive screw part of a motor operated valve used in a refrigerating cycle or the like.

A motor operated valve 1 has a can 10, in its outer side, a motor mold 20 is mounted. The motor mold 20 has a stator yoke 21, a magnet wire 22 is connected to a control device in the outside through a lead wire 36. A valve holder 70 integral with rotors 62, 60 has a hollow part 71, to slidably support a valve element 80 inserted in the hollow part 71. A bush 90 secured to a valve main body 40 has an internal thread 92, an external thread part 74 of the valve holder 70 is screwed. In the hollow part 71 of the valve holder 70, a coil spring 72 is inserted, a disk-shaped washer 100 arranged between the coil spring 72 and the valve holder 70 functions as a thrust bearing, sliding generated between the valve holder 70 and the valve element 80 is smoothed.
