<p><P>PROBLEM TO BE SOLVED: To provide a female screw member and the like in which misalignment does not occur between a female screw part and a lower end part of a female screw member of a motor-operated valve, consequently the occurrence of burr can be prevented and which therefore achieves reduction in manufacturing costs of a motor-operated valve and the like. <P>SOLUTION: The female screw member 1 includes: the female screw part 1b in which a female screw 1a is formed; a cylindrical part 1h having an inner diameter larger than an outer diameter of the female screw; and a connecting part 1g connecting the female screw part and the cylindrical part together so as to have a gap penetrating in the axial direction thereof and having an acting surface, wherein the connecting part is formed in such a manner that the leading end of the acting surface is made flush with or to be recessed from an end part of the female screw part. The female screw part and the cylindrical part may be constituted in such a manner that: they have a plurality of connecting parts 31g and 31q connecting so as to have a gap penetrating in the axial direction; one connection part 31g has an acting surface made flush with or to be recessed from the end part of the female screw part; and a connecting part 31q having no acting surface in the plurality of connecting parts is formed so as to be recessed from the leading end of the connecting parts having the acting surface. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
