Abstract
An on-vehicle detector includes a torque detecting portion for magnetically detecting a torque transmitted to a rotating shaft rotated by steering operation, and a rotation detecting portion for magnetically detecting a rotation of the rotating shaft. The rotation detecting portion includes a magnet with a pair of magnetic poles and a magnetic detection element, the magnet being disposed on a side of the rotating shaft so as to rotate simultaneously with the rotating shaft and the magnetic detection element being disposed on a side of the rotating shaft to detect a change in magnetic flux density caused by the magnet approaching or moving away in accordance with the rotation of the rotating shaft. The magnet is disposed such that the pair of magnetic poles is aligned along a circumferential direction of the rotating shaft.
