The cage includes a small-diameter annular portion on one axial side, a large-diameter annular portion which is positioned on the other axial side and on the outer side in the radial direction of the large flange, and a plurality of column portions. An outer diameter of an axial inner surface included in the large-diameter annular portion is greater than a diameter of a virtual circle that links outer end portions in the radial direction of the cavity portions of the plurality of taper rollers.
