Abstract / Hauptanspruch
A position detector includes a magnet disposed between first ends of first and second magnetic flux transmission parts and a magnet disposed between second ends of the first and second magnetic flux transmission parts. The position detector also includes a Hall IC that is positioned within a gap and moves relative to a rotating body. The Hall IC detects a density of the magnetic flux from the first and second magnetic flux transmission parts and outputs a signal according to the density of the magnetic flux passing therethrough in order to detect a position of a detection object. A minimum magnetic flux density position within the gap may be shifted to a position having the highest detection accuracy such that the position detection accuracy of the detection object is improved.
