The present invention relates to a torque sensor device for a vehicle, comprising: a rotor part connected to and rotating on one of an input shaft and an output shaft; a stator part arranged to face the rotor part and connected to the other one of the input shaft and the output shaft to rotate; a first measuring part that measures the amount of change in a magnetic field according to a relative rotational displacement of the rotor part and the stator part; and a second measuring part that is disposed outside the first measuring part to shield the first measuring part from external magnetic fields, and measures the amount of change in the magnetic field according to the relative rotational displacement of the rotor part and the stator part, thereby capable of preventing deterioration of sensing performance due to external magnetic fields.

    본 발명은 차량용 토크 센서 장치에 관한 것으로, 입력축과 출력축 중 어느 하나에 연결되어 회전하는 로터부와, 로터부와 마주보게 배치되고, 입력축과 출력축 중 나머지 하나에 연결되어 회전하는 스테이터부와, 로터부와 스테이터부의 상대 회전 변위에 따른 자기장의 변화량을 측정하는 제1측정부 및 제1측정부의 외측에 배치되어 외부 자계로부터 제1측정부를 차폐하고, 로터부와 스테이터부의 상대 회전 변위에 따른 자기장의 변화량을 측정하는 제2측정부를 포함하는 것을 특징으로 한다.
