Beschreibung
Zusammenfassung:	A magnetic path forming member is formed by heating a radially intermediate portion of a workpiece made of a magnetic material to melt the radially intermediate portion from one axial face of the workpiece to the other axial face of the workpiece to form a keyhole, and disposing an alloy element in a molten pool around the keyhole to demagnetize a melted portion.
