Abstract
The present disclosure relates to a torque sensor configured to axially magnetize a magnet and simplify a stator structure facing the magnet, whereby dimensions and shapes of members capable of collecting magnetism can be easily controlled to provide a torque sensor excellent in operational reliability, the torque sensor including a ring-shaped and axially-magnetized magnet connected to one of an input shaft of a steering wheel and an output shaft; and a stator including a ring-shaped body axially discrete from the magnet and a plurality of holes vertically penetrating the body, whereby structure of the torque sensor is simplified to enhance a concentrated efficiency of magnetic change.
