Abstract: Disclosed is a torque rotor and method for manufacturing the torque rotor having an effect of preventing inflow of plastic between a yoke and a magnet during a conventional plastic injection molding process for forming an assembling structure after assembling between the yoke and the magnet, thereby preventing degradation of a roundness of the magnet or damage of the magnet due to the difference in the temperature expansion coefficients, and preventing idle rotation of the yoke and the magnet relative to each other.

Abstract: A steering angle sensor and a vehicle system having the sensor are disclosed. The steering angle sensor for mounting on a vehicle comprises a main gear coupled to and rotated with a steering column; a first auxiliary gear and a second auxiliary gear meshed with the main gear, respectively; angular detection means mounted adjacent to the first and the second auxiliary gears respectively for generating electric signals in concert with rotations of the first and the second auxiliary gears; and a calculation/control module for calculating steering angles from the electric signals generated by the angular detection means, determining a duty ratio corresponding to the steering angle and generating a rough gain pulse width modulation signal and a fine gain pulse width modulation signal.
