摘要：There is provided a rolling bearing which suppress a sealing member fromentering into the inside of the rolling bearing so as to effectively prevent contaminantsfrom entering into the rolling bearing and to avoid the increase of its rotational torque.

The rolling bearing has a configuration in which a plurality of rollers (30) are retained in araceway space (29) between an inner ring (10) and an outer ring (20). Openings at bothends in an axial direction of the track space (29) are sealed with sealing members (60), andmetal shield members (70) are arranged at the outer sides in the axial direction of thesealing members (60). Each of the sealing members (60 is fixed on the outer ring (20) bysandwiching outer circumferential edge portion of the sealing member (60) between eachof the metal shield members (70) and the outer ring (20). The sealing members (60) aresuppressed from entering into the inside of the rolling bearing by forming each sealingmember (60 to have a three-dimensional shape curved convexly inward between theouter circumferential edge portion and inner circumferential edge portion, and causingthe inner circumferential edge portions to elastically be in surface contact with taperedsurfaces of collars (40) from the outside.
