A tapered roller bearing (1) used in transmissions or differentials for automobiles includes an inner ring (2), an outer ring (3), a plurality of tapered rollers (4) rollably disposed between the inner and outer rings (2 and 3), and a cage (5) for holding the tapered rollers (4) at circumferential predetermined intervals, wherein the roller coefficient ³ exceeds 0.94, where ³ is (the number of rollers x mean roller diameter) / (À x PCD). |
