Abstract
A torque sensor includes an input rotation component, which rotates with a steering column input shaft and is provided with a first conducting part, an output rotation component which rotates with a steering column output shaft and is provided with a second conducting part, and an electromagnetic carrier positioned in a positionally fixed manner and provided with a magnetic field generating component and a magnetic field detection component. The magnetic field generating component generates a magnetic field penetrating the first conducting part and the second conducting part, the magnetic field detection component detects a change in the magnetic field caused by a change in the positions of the first and second conducting parts in the magnetic field when the steering column is under torsional stress, and the steering torque is determined on the basis of the detected change in the magnetic field.
