Zusammenfassung:	A tapered roller bearing (11) is provided with: an outer ring (12) having an outer ring raceway surface (12a) on the inner peripheral surface; an inner ring (13) having an inner ring raceway surface (13a) on the outer peripheral surface; a plurality of tapered rollers (14) arranged so as to be rollable between the outer ring raceway surface (12a) and the inner ring raceway surface (13a); and a cage (15) having a plurality of pockets for housing and holding the plurality of tapered rollers (14) at predetermined intervals. Among four ends of a small-diameter-side end and a large-diameter-side end of an outer ring raceway surface (12a) of the outer ring (12) and a small-diameter-side end and a large-diameter-side end of an inner ring raceway surface (13a) of the inner ring (13), a flange portion (12b) protruding inward in the radial direction is formed at the large-diameter-side end of the outer ring raceway surface (12a) of the outer ring (12), the contact angle being 40-50 DEG, and the contact angle being 40-5
