On-vehicle detector

摘要

An on-vehicle detector (1) includes a torque detecting portion (2) for magnetically detecting a torque transmitted to a rotating shaft (11) rotated by steering operation, and a rotation detecting portion (3) for magnetically detecting a rotation of the rotating shaft (11). The rotation detecting portion (3) includes a magnet (33) with a pair of magnetic poles and a magnetic detection element (34), the magnet (33) being disposed on a side of the rotating shaft (11) so as to rotate simultaneously with the rotating shaft (11) and the magnetic detection element (34) being disposed on a side of the vehicle to detect a change in magnetic flux density caused by the magnet (33) approaching or moving away in accordance with the rotation of the rotating shaft (11). The magnet (33) is disposed such that the pair of magnetic poles is aligned along a circumferential direction of the rotating shaft (11).
