Provided is a torque sensor device which is placed between an input shaft and an output shaft and detects the torque between the input shaft and the output shaft by means of the relative rotation displacement between the input shaft and the output shaft. A torque sensor device comprises: a housing which accommodates end portions of an input shaft and an output shaft, is position-fixed, and is rotatable relative to the input shaft and the output shaft; a magnet unit having a magnet block that is accommodated in the housing by being position-fixed therein; a collector unit having parts thereof connected to the input shaft and the output shaft, respectively, being placed so as to rotate together, and having a collector of which one or more parts are placed between the input and output shafts and the magnet block in the radial direction of the input and output shafts so as to focus a magnetic field of the magnet unit; and a sensing unit having a torque sensor which is placed around the perimeter of the collector unit and detects the magnetic field focused by means of the collector unit. |
