PROBLEM TO BE SOLVED: To prevent abrasion of a cage, by ensuring strength of a column part of the cage. SOLUTION: A tapered face part 7a whose inside diameter is enlarged is formed in an inner circumferential side of a conical ring of an end face 7 in a circumferential direction of each pocket 5 of the cage 6. Only the tapered face part 7a is mid-high in an axial direction, and the mid-high part is brought into contact with a tapered face of the tapered roller bearing 4. Therefore, the strength of the column part 8 is ensured by forming the column part 8 to have a fixed width without constriction part, and the abrasion of the cage is prevented.
