摘要： In a conductive rolling bearing comprising an inner ring (11), an outer ring (12), a plurality of rolling elements (13) mounted between the inner ring and the outer ring, and seal members for sealing the space between the inner ring and the outer ring, the seal members have one end thereof secured to one of the inner ring and the outer ring and the other end thereof in an elastic, sliding contact with a seal wall surface (18) formed on the other. The free end (19) of the seal member (15) is bent outwardly of the bearing and the seal member (15) is in a sliding contact with the seal wall surface (18) on its bent portion (20). This arrangement gives the effects of providing a low, stable torque for the bearing and of improving the seal performance of the bearing. This conductive rolling bearing is used in a steering assembly of an automobile and bearing assemblies having a bearing near electrical devices.
