Abstract
A torque sensor includes a first shaft, a second shaft that is coaxially linked to the first shaft, a cylindrical magnet that rotates integrally with the first shaft, a pair of magnetic yokes that rotate integrally with the second shaft, and three magnetic sensors that respectively detect a change in magnetic flux of the magnetic yokes for calculating torque applied to the first and second shafts. Output characteristics of the three magnetic sensors are different from each other.
