Abstract

See full text

An axial-type magnetic encoder includes an annular fixing member that is fabricated by press molding, and an annular plastic magnet that is attached by injection molding to a sensor-opposed surface of the annular fixing member. When the annular fixing member includes a cylindrical part and an inward flange part extended radially inward from an end edge of the cylindrical part, the magnetic encoder has a high-form accuracy surface on the sensor-opposed surface more radially outward than a range of a diameter (d−2·r) determined by an inner diameter d of the cylindrical part and a radius r of a corner between the cylindrical part and the inward flange part. An outer diameter of the annular plastic magnet is positioned on the high-form accuracy surface.
