<P>PROBLEM TO BE SOLVED: To provide a tapered roller bearing superior in assembling performance, while reducing rotational torque by reducing agitating resistance of lubricating oil, by regulating a lubricating oil quantity on an inner ring raceway surface to a proper quantity, regardless of the rotational direction of a bearing. Ž<P>SOLUTION: This tapered roller bearing has a straightening plate 37 extended toward the inner ring raceway surface 2a from an inner diameter surface 35a of a column part 35 of a cage 33 for holding a mutual interval of tapered rollers 4. This straightening plate 37 is set smaller than the column part 35 in a dimension in the peripheral direction, and is equipped so as to partition an intermediate part between the tapered rollers 4, and the excessive lubricating oil is discharged to the outer ring 3 side by the tip 37a in close vicinity to the inner ring raceway surface 2a.
