Magnetic rotational angle detecting apparatus

摘要

A detector for detecting a rotational angle of a gearshift lever. The detector includes a magnet that forms a magnetic flux in a predetermined direction along its surface. A magnetic resistance sensor generates a detection signal corresponding to the direction of the magnetic flux. The detected object is connected to the magnet or the magnetic resistance sensor. The magnet and the magnetic resistance sensor are rotated relatively to each other to generate the detection signal and obtain the rotational angle of the detected object. The magnetic resistance sensor is separated from an axis of rotation of the sensor or the magnet.
