The present invention provides a torque sensor device disposed between an input shaft and an output shaft and configured to detect a torque between the input shaft and the output shaft through a relative rotation displacement therebetween, the torque sensor device comprising: a housing configured to accommodate an end of the input shaft and an end of the output shaft and fixed in position to be able to perform a relative rotation with respect to the input shaft and the output shaft: a magnet unit rotatably accommodated in the housing in such a manner as to be connected to one end of one of the input shaft and the output shaft; a collector unit rotatably accommodated in the housing in such a manner as to be at least partially connected to one end of the other of the input shaft and the output shaft, the collector unit being configured to form a magnetic circuit together with the magnet unit; and a sensing unit including a torque sensor disposed at the outer circumference of the collector unit and configured to detect a magnetic field focused by the collector unit, wherein the collector unit comprises a lower collector including an annular lower collector ring disposed radially and circumferentially at one end of the other of the input shaft and the output shaft.
