A tapered roller bearing comprising: an outer ring having a tapered outer raceway surface formed on an inner peripheral face of the outer ring; an inner ring having a tapered inner raceway surface formed on an outer peripheral face of the inner ring; a plurality of tapered rollers rollably disposed between the outer raceway surface and the inner raceway surface; and a cage that holds the tapered rollers at equal intervals in a circumferential direction of the tapered roller bearing, characterized in that a small-diameter-side inner periphery end portion of the cage is located at a position inward of an axially outer end face of the inner ring in an axial direction of the tapered roller bearing, a small-diameter-side end face of the cage has an inwardly tilted face that is tilted inward in the axial direction from the inner periphery end portion from a radially inner side to a radially outer side, and an outwardly tilted face, the inwardly tilted face being formed in a radially inner region of the small-diameter-side end face, and the outwardly tilted face being formed in a radially outer region of the small-diameter-side end face; a small-diameter-side outer periphery end portion of the cage has a first corner at which the outwardly tilted face and a small-diameter-side outer peripheral face of the cage meet each other at an acute angle (θ); a small-diameter-side inner periphery end portion of the cage has a second corner at which the inwardly tilted face and a small-diameter-side inner peripheral face of the cage meet each other at an acute angle; and the length of the outwardly tilted face is greater than the length of the inwardly tilted face, in a section taken along the axial direction. an outer ring having a tapered outer raceway surface formed on an inner peripheral face of the outer ring; an inner ring having a tapered inner raceway surface formed on an outer peripheral face of the inner ring; a plurality of tapered rollers rollably disposed between the outer raceway surface and the inner raceway surface; and a cage that holds the tapered rollers at equal intervals in a circumferential direction of the tapered roller bearing, characterized in that a small-diameter-side inner periphery end portion of the cage is located at a position inward of an axially outer end face of the inner ring in an axial direction of the tapered roller bearing, a small-diameter-side end face of the cage has an inwardly tilted face that is tilted inward in the axial direction from the inner periphery end portion from a radially inner side to a radially outer side, and an outwardly tilted face, the inwardly tilted face being formed in a radially inner region of the small-diameter-side end face, and the outwardly tilted face being formed in a radially outer region of the small-diameter-side end face; a small-diameter-side outer periphery end portion of the cage has a first corner at which the outwardly tilted face and a small-diameter-side outer peripheral face of the cage meet each other at an acute angle (θ); a small-diameter-side inner periphery end portion of the cage has a second corner at which the inwardly tilted face and a small-diameter-side inner peripheral face of the cage meet each other at an acute angle; and the length of the outwardly tilted face is greater than the length of the inwardly tilted face, in a section taken along the axial direction.
