This tapered roller bearing (1) is provided with an inner race (2), an outer race (3), multiple tapered rollers (4), and a ring-form cage (10). The cage (10) comprises a small-diameter ring (11) to one side in the axial direction, a large-diameter ring (12) to the other side in the axial direction and positioned radially outside of a large flange (6) on the inner race (2), and multiple pillars (13) which link the small-diameter ring (11) and the large-diameter ring (12). Between the large flange (6) and the large-diameter ring (12), the tapered roller bearing (1) has a labyrinth structure (K3) that suppresses the flow of lubricant from inside of the bearing to outside of the bearing. |
