TORQUE DETECTING APPARATUS

摘要

A torque detecting apparatus detects a torque applied to a first shaft, based on a relative rotational displacement between the first shaft and a second shaft caused by torsion in a coupling shaft which couples the first shaft and the second shaft. The torque detecting apparatus includes: first and second magnets which are coupled to the first shaft and the second shaft so as to rotate together with the first shaft and second shaft, respectively; and a plurality of magnetic sensors which are disposed between the first magnet and the second magnet and which detect a rotational angle of the first shaft and a rotational angle of the second shaft.
