<p>PROBLEM TO BE SOLVED: To provide a conical roller bearing which can prevent a fall of rollers at assembling, has a high-load capacity and can reduce a size in a structure which does not have a small flange.SOLUTION: A conical roller bearing 1 comprises: an inner ring 2 having a tapered raceway face 2a at an external peripheral face; an outer ring 3 having a tapered raceway face 3a at an internal peripheral face; a plurality of conical rollers 4 which roll between the raceway face 2a and the raceway face 3a; and a cage 5 for rollingly holding the conical rollers 4 in a pocket part. The inner ring 2 has a structure which does not have a small flange at a small-diameter side end part, the cage 5 has a guide part and a fall prevention part of the conical rollers 4 at the pocket part, and the conical rollers 4 are assembled to the pocket part through the elastic deformation of the fall prevention part, and integrated with the cage 5.</p> |
