PROBLEM TO BE SOLVED: To provide an electric expansion valve attaining smoother turning of a magnetic rotor without receiving an axial force. SOLUTION: The electric expansion valve includes the magnetic rotor 3 and a shaft 4, and further includes an output shaft 5. The magnetic rotor 3 is surroundingly provided on the output shaft 5, and the output shaft 5 is slidably connected to the shaft 4 in an axial direction and drivably connected to the shaft 4 in a circumferential direction. The magnetic rotor 3 can thereby be smoothly rotated without receiving the axial force transmitted by the shaft 4. COPYRIGHT: (C)2011,JPO&INPIT
