Claim:
A conveyor bearing comprising: an inner ring fitted on and fixed to a shaft; a plurality of rolling elements disposed rollably on a raceway surface of the inner ring; an outer ring disposed rotatably relative to the inner ring via the rolling elements; and a seal member to seal in a grease between the outer ring and the inner ring, wherein the conveyor bearing is configured such that the outer ring rotates during use, the seal member comprises a first L-shaped annular member and a second L-shaped annular member, each of the L-shaped annular members having an L-shaped radial section, with a given interval therebetween to oppose each other in an axial direction of the conveyor bearing, and the first L-shaped annular member comprising a first cylindrical portion fixed to an inner circumferential surface of an axially outer end portion of the outer ring and a first disc portion extending radially inwards from an axially inner end of the first cylindrical portion, the second L-shaped annular member comprising a second cylindrical portion fixed to an outer circumferential surface of an axially outer end portion of the inner ring and a second disc portion extending radially outwards from an axially outer end of the second cylindrical portion at a location spaced outward from the first disc portion in the axial direction, a seal lip is fitted to the first L-shaped annular member, the seal lip comprising: a lip portion contacting the second disc portion of the second L-shaped annular member; and a protruding portion provided on an outer circumferential side of the lip portion so as to form a gap between a distal end of the protruding portion and to be completely separated from the second disc portion of the second L-shaped annular member, wherein the second L-shaped annular member is shaped so as to not extend in the axial direction over a top surface of the protruding portion.
