摘要: A magnetization yoke having an exciting coil wound thereon is arranged to hold a magnetic member and metal ring so that flux passes through magnetizes the in portion held by for successively magnetizing along circumferential direction thereby multipolarly direction. Thus, encoder large strength small pitch error, wheel bearing employing same method of manufacturing can be obtained.
