Abstract

The conical roller bearing includes an inner ring which includes an annular groove between an inner-ring-side raceway surface and a small-diameter-side end portion thereof, and a cage which includes an erected portion extending from a first annular portion of the cage towards the annular groove. The erected portion includes a first inclined portion and a second inclined portion. The first inclined portion is inclined towards conical rollers disposed in pockets of the cage while extending from the first annular portion towards the annular groove. The second inclined portion is inclined towards the small-diameter-side end portion while extending from the first inclined portion towards the annular groove. The second inclined portion is configured to be brought into engagement with the annular groove in an axial direction of the inner ring.
