Zusammenfassung:	An object is to prevent tapered rollers from being placed into pockets inversely with their large-diameter side and the small-diameter side flipped upside down when the tapered rollers are assembled into the pockets from a diametrically inner surface side of a retainer. A retainer (20) of a tapered roller bearing (11) includes a large-diameter ring portion (20a) on its large-diameter side, a small-diameter ring portion (20b) on its small-diameter side, and a plurality of pillar portions (20c) disposed equidistantly in a circumferential direction, connecting the large-diameter ring portion (20a) and the small-diameter ring portion (20b). Each pillar portion (20c) has, on its diametrically inner surface side of its small-diameter end portion, a fall-out prevention tab (20e) that prevents the tapered roller (14) assembled into the pocket (P) from falling onto the diametrically inner surface side.
