Abstract
A rotor assembly of a torque sensor includes: a rotor having a through hole formed along an axial direction so that a steering shaft can be inserted in the through hole; a gear having substantially a ring shape and coupled to the rotor; and a fixing portion configured to fix the rotor to the gear. The fixing portion includes at least one first coupling portion configured to fix the rotor to the gear with respect to the axial direction, and at least one second coupling portion configured to fix the rotor to the gear with respect to a rotation direction. Each of the first coupling portion includes an elastically deformable hook bent from the rotor, and a hook groove penetrating the gear or being depressed from a surface of the gear in a radial direction, such that the hook is inserted in and caught by the hook groove.
