軸受構造。By energizing the stator coil 13 of the motor fixed to the outer periphery of the case 10 made of a non-magnetic material, the rotor 5 of the motor, which is integrally formed with the valve shaft 1 having the male thread 4 housed inside the case 10, is activated. In an electric valve that controls the opening degree of the valve seat 2 by rotating the valve shaft 1 and converting this rotation into a linear motion of the valve shaft 1 by a propulsion bearing 9 having a female thread 8, the rotor 5 is mounted on the end face of the rotor 5. A bearing structure for an electric valve characterized in that a flange portion 17 made of a thin resin low-friction material and having an outer diameter smaller than the inner diameter of the case 10 is provided.
