ABSTRACT:
A torque sensor including a first step formed on an inner peripheral surface of a sensor housing, a second step formed on an outer peripheral surface of a detection coil assembly, the first and second steps axially supporting each other, and a groove formed on the outer peripheral surface of the detection coil assembly at a position adjacent to the second step such that the groove faces an inner surface portion of the first step, so that the first step penetrates the groove while being plastically deformed when the detection coil assembly is pressed toward the first step, thereby causing the detection coil assembly to be fixed to the inner peripheral surface of the sensor housing. Since the detection coil assembly is fixed in the sensor housing through the structural modification of the sensor housing and detection coil assembly, without using a separate fixing member, it is possible to effectively achieve the fixing of the detection coil assembly, and thus, to reduce the number of elements in the torque sensor.
