のオイルを必要とする事は公知である。2. Description of the Related Art Bearings used for vehicle transmissions are required to have a large capacity as the output of vehicles has increased in recent years. Since tapered roller bearings can be used with a large capacity in a compact space, their use tends to increase. Further, it is known that the tapered roller bearing has a smaller rolling contact surface of the roller than the cylindrical roller bearing and the oil easily flows due to centrifugal force, so that the oil retaining force is weak and more oil is required. is there.
