Beschreibung
Zusammenfassung:	A thrust bearing device includes: a thrust collar fitted with a drive shaft, the thrust collar including a flange portion extending radially outward of the drive shaft; and a thrust member penetrated by the thrust collar and including a pad portion in a region facing the flange portion. The pad portion includes: a plurality of land portions which are parallel to a plane orthogonal an axis of the drive shaft and are disposed at intervals in a circumferential direction of the drive shaft; and tapered portions each of which is disposed between adjacent land portions among the plurality of land portions, joined via a step to a boundary of one land portion in the circumferential direction of the drive shaft, and joined continuously to a boundary of another land portion. Each of the land portions has a circumferential groove which is longer in the circumferential direction than in a radial direction of the drive shaft.
