Abstract
A position detecting sensor for detecting a position of a magnetic body includes a first yoke, a first pair of magnets respectively possessing first and second poles and provided at both sides of the first yoke, a magnetic detecting element located at a distant position at a right angle from a center portion on a line connecting the first pair of magnets. The first pole of one of the first pair of magnets faces one side of the first yoke and the second pole of the other one of the first pair of magnets faces the other side of the first yoke. The first pole of the one of the first pair of magnets is the same as the first pole of the other one of the first pair of magnets.
