Abstract
A permanent magnetfor biasing is placed between opposite surfaces of a second stationary magnetic bodyand a third stationary magnetic body, and a range in magnetic flux density detected by a magnetic sensoris changed to thus include zero in the magnetic flux density. A correction and an adjustment of a temperature characteristic and so on of the magnetic sensorare performed in a state of zero in the magnetic flux density.
