PROBLEM TO BE SOLVED: To simplify a structure of an electrically-driven valve of which valve opening is controlled by a motor; to reduce a number of components; to improve accuracy of concentricity of a movable side member and a fixed side member; and to enhance smoothness of valve opening and closing operation. SOLUTION: The electrically-driven valve 1 is provided with a valve body 10 forming a valve chest 12, and the valve body 10 is formed as a component wherein a stem 20 is integrally press-formed. A fixing screw member 80 is attached to the stem part 20. A rotor member 60 is connected to a screw shaft 70, and the screw shaft 70 supports a valve holder 90. The valve holder 90 supports a valve element 100, and a spring 112 and a ball 110 pushes the valve element 100. A valve seat member 30 has a solder flow groove 36 around it, and pipes 40 and 42 are provided with dimples 40a and 42a. COPYRIGHT: (C)2007,JPO&INPIT
