Abstract
Magnetic field generating unit is fixed to object that moves relative to magnetic field detecting means. Magnetic field generating unit has magnetic field generator, first support structure that is fixed to object and second support structure that is independent of first support structure. Second support structure is supported by first support structure and supports magnetic field generator. For example, second support structure is formed of a nonmagnetic material, and magnetic field generator is arranged away from first support structure.
