Beschreibung
Zusammenfassung:	A tapered land thrust bearing device with a land surface having a substantially reduced area without changing the contour shape of the land surface even if the area of the land surface is small, and high mechanical efficiency, as well as a turbocharger provided with the bearing device. A tapered land thrust bearing device includes: a flange portion fitted onto a rotary shaft and including a first thrust portion; and a thrust member including a second thrust portion which is disposed around a through hole and which faces the first thrust portion of the flange portion.
