[ What is claimed is:] [1.] A tapered roller bearing comprising:an outer ring having a conical raceway surface;an inner ring having a conical raceway surface, a retaining rib face at small diameter side of the raceway surface, and a cone back face rib face at large diameter side of the raceway surface;a plurality of tapered rollers disposed for rolling between the raceway surface of the outer ring and the raceway surface of the inner rings; anda cage for retaining the tapered rollers at predetermined circumferential intervals,wherein during operation of the bearing, large end faces of the tapered rollers are contacted and guided by the cone back face rib face of the inner ring, and whereinthe retaining rib face of the inner ring is a surface which is parallel to small end faces of the tapered rollers disposed on the raceway surface of the inner ring and which defines one end of a raceway groove width of the inner ring defining the range of axial movements of the tapered rollers.
