ABSTRACT:
A steering angle sensor including a case body having a through hole for a steering shaft. The case body is adapted to be fixed to a vehicle body. A cover is attached to an end portion of the case body and a printed board having a flat resistor element is provided at the end portion of the case body. A hollow rotor for passing the steering shaft therethrough is rotatably supported by the case body and the cover, and the hollow rotor has a positioning portion for positioning the steering shaft. A contactor is mounted on the rotor within the cover and disposed in sliding contact with the resistor element of the printed board. A spring is interposed between the steering shaft and the rotor to apply a resilient force thereto. The resistor element has a degree of variation of a sensor output voltage in a first range of steering angles, in straight running of a vehicle, larger than that in a range of steering angles exceeding the first range.
