Abstract: Disclosed is a torque angle sensor and an electronic power steering apparatus having the torque angle sensor, which includes an upper case, an upper side of which is assembled with a sensor housing, a rotor assembled with an inside of the upper case, the rotor fitted around an outer surface of the output shaft extending through the rotor and assembled with an inside of the upper case, a lower case, a lower side of which is assembled with a spacer cover, and a middle case assembled between the upper case and the lower case. The upper case includes holding parts opposed to each other and formed on an upper surface of the upper case, which is assembled with the sensor housing, and a seating spring protruding downward with inclination from an end of one of the holding parts and elastically bent when the upper case is assembled with the sensor housing.
