<p>PROBLEM TO BE SOLVED: To provide a holder for a conical roller bearing and a conical roller bearing, capable of stabilizing rotation of the holder by preventing a contact between a large diameter-side end face portion of a conical roller and a large diameter-side annular portion of the holder during rotation of the bearing.SOLUTION: The conical roller bearing includes a large diameter-side annular portion 15, a small diameter-side annular portion 16 disposed coaxially with the large diameter-side annular portion 15, a plurality of pillar portions 17 disposed at nearly equal intervals in the circumferential direction so as to connect the large diameter-side annular portion 15 with the small diameter-side annular portion 16, and pocket portions 18 formed between the pillar portions 17 adjacent to each other in the circumferential direction, and rollably retaining a conical roller 13. A plurality of fin portions 20 are radially disposed at nearly equal intervals in the circumferential direction on an axial outer end face 16a of the small diameter-side annular portion 16.</p> |
