Abstract: A tapered roller bearing improves durability during a state of insufficient lubrication by sufficiently lengthening the time until rotation becomes impossible due to seizure. Oil retaining concave sections, recessed outward in the radial direction, are formed in portions on the inner circumferential surface of a large-diameter rim section of the retainer whose phase in the circumferential direction coincides with the pockets. A portion of the bottom surface of each of the oil retaining concave sections, open to the inside surface of the pocket, face a concave section formed in an end surface on the large-diameter side of tapered roller that is held inside the pocket. When lubrication becomes insufficient, oil remaining in the concave sections is effectively used for lubricating areas of sliding contact between the end surfaces on the large-diameter side and the inside surface in the axial direction of a large-diameter side flange section.
