Noncontact rotary position sensor

The invention relates to a compact, noncontact rotary position sensor that accurately detects a rotary position of a rotating object. A magnetism throttling portion (16, 17) is provided in a midway point of a magnetic path. Two magnetic induction elements (21, 22) are disposed adjacently each other at the magnetism throttling portion (16, 17). This arrangement effectively allows a magnetic flux to converge at the location, at which the magnetic induction elements (21, 22) are mounted. A noncontact rotary position sensor offering high sensitivity and high accuracy can then be obtained. It is also possible to simplify routing of signal lines from the two magnetic induction elements (21, 22), since the two magnetic induction elements (21, 22) are adjacent to each other.
