A rolling bearing characterized by comprising: an inner member having an inner race surface; an outer member having an outer race surface which forms an annular raceway space between the outer race surface and the inner race surface; a plurality of rolling elements arranged in the raceway space; flexible annular sealing members which close openings at both ends in an axial direction of the raceway space respectively; and annular metal shield members provided at outer sides of the sealing members in the axial direction respectively, wherein each of the sealing members has an outer circumferential edge portion and an inner circumferential edge portion which contacts an outer surface of the inner member; each of the sealing members is formed in a three-dimensional shape such that the sealing member in a natural state is convex inwardly in the axial direction between the outer circumferential edge portion and the inner circumferential edge portion, wherein the inner circumferential edge portion of the sealing member projects in a direction opposite to the raceway space and is elastically in surface contact with the outer surface of the inner member when the sealing member is fixed to the outer member; and each of the metal shield members is fixed to the outer member in a state that the outer circumferential edge portion of each sealing member is sandwiched between the metal shield member and the outer member; characterized in that each of the metal shield members covers at least part of each sealing member such that an annular gap is formed in the axial direction between the sealing member and the metal shield member without contacting the outer surface of the inner member so that there is an annular gap between an inner circumferential edge portion of the metal shield member and the outer surface of the inner member. an inner member having an inner race surface; an outer member having an outer race surface which forms an annular raceway space between the outer race surface and the inner race surface; a plurality of rolling elements arranged in the raceway space; flexible annular sealing members which close openings at both ends in an axial direction of the raceway space respectively; and annular metal shield members provided at outer sides of the sealing members in the axial direction respectively, wherein each of the sealing members has an outer circumferential edge portion and an inner circumferential edge portion which contacts an outer surface of the inner member; each of the sealing members is formed in a three-dimensional shape such that the sealing member in a natural state is convex inwardly in the axial direction between the outer circumferential edge portion and the inner circumferential edge portion, wherein the inner circumferential edge portion of the sealing member projects in a direction opposite to the raceway space and is elastically in surface contact with the outer surface of the inner member when the sealing member is fixed to the outer member; and each of the metal shield members is fixed to the outer member in a state that the outer circumferential edge portion of each sealing member is sandwiched between the metal shield member and the outer member; characterized in that each of the metal shield members covers at least part of each sealing member such that an annular gap is formed in the axial direction between the sealing member and the metal shield member without contacting the outer surface of the inner member so that there is an annular gap between an inner circumferential edge portion of the metal shield member and the outer surface of the inner member.
