The present invention provides a torque sensor device. The torque sensor device comprises a sensing unit including a torque sensor sensing a change in a magnetic field, which is generated by the rotation of a magnet unit including a magnet ring. The magnetic ring is received in a housing receiving an end of an input shaft and an end of an output shaft, is arranged on a fixed position to be relatively rotated with respect to the input shaft and the output shaft, and is connected to one end of one of the input shaft and the output shaft to be rotated inside the housing. The magnet unit comprises: a magnet holder; and the magnet ring. The magnet holder has one end connected to the input shaft. The magnet ring is arranged at an interval while placing the magnet holder therein. The magnet holder comprises: a magnet holder shaft having one end connected to the input shaft; and a magnetic holder base arranged on the other end of the magnet holder shaft and allowing the magnet ring to be arranged on both sides. The magnet ring has a ring body pit formed on the inner circumferential surface thereof. The magnet holder base has a holder base body pit formed on one surface of a holder base body connected to the magnet holder shaft to be engaged with the magnet ring body pit. |
