<P>PROBLEM TO BE SOLVED: To prevent discharge between a can and a stator of a motor-operated valve reliably for a long period of time. <P>SOLUTION: A stator 11 for a motor-operated valve is mounted on a motor-operated valve main body. The motor-operated valve main body includes: a valve main body 14 that has a valve seat 12a and a valve chest 12; fluid inlet/outlet pipes 7 and 8 that are provided in the valve main body 14; a valve 13a that is rotary-driven by a rotor 16 that is provided rotatably in the valve main body 14; and a can 21 that is provided in the valve main body 14 so as to cover the rotor 16 and the valve 13a. The stator 11 includes: a resin mold portion 2 that covers a yoke 3a and coils 3b; an opening 2c that is provided on a bottom surface of the resin mold portion 2 so as to expose a portion 3c of a lower surface of the yoke 3a; and a detent member 5 that has a convex portion 5b that is in contact with the yoke 3a through the opening 2c, and an engagement portion 5e that is engaged with one of the fluid inlet/outlet pipes 7 and 8. The detent member 5 is mounted on the resin mold portion 2, and then fixed to the resin mold portion 2 in such a manner that a perimeter of the convex portion 5b is in intimate contact with an entire circumference of the opening 2c. <P>COPYRIGHT: (C)2012,JPO&INPIT |
