PROBLEM TO BE SOLVED: To provide a conical roller bearing which can reduce a torque loss by properly suppressing a flow-in amount of a lubricant which flows into an internal space of the bearing. ! SOLUTION: A conical roller bearing 1 comprises an inner ring 2, an outer ring 3, a plurality of conical rollers 4 interposed between the inner ring 2 and the outer ring 3, and a cage 10 having pockets 14 for accommodating the conical rollers 4. A small-diameter annular part 11 of the cage 10 blocks a small-diameter side opening part A1 which is formed of a small flange part 5 arranged at an axial one-end side of the inner ring 2 and an axial one end part of the outer ring 3 so as to limit the lubricant from flowing into the bearing internal space S more than necessary. At a radial outside face 13a of a columnar part 13, there are formed slide-contact faces 15, 16 for positioning the cage 10 to a radial direction by an outer ring raceway face 3a by slide-contacting with the outer ring raceway face 3a, and also th |
