<p>The present invention provides a thrust bearing device by which it is possible to reduce the amount of lubricant supplied while maintaining the maximum temperature of a pad surface at or below an allowable value. This thrust bearing device receives a load in the axial direction of a rotational axis via a thrust collar that is disposed to the outer peripheral side of the rotational axis and that is fixed to a bearing base, the thrust bearing device being characterized in that the thrust bearing is provided with a thrust plate having a plurality of pad surfaces facing the thrust collar in the axial direction, an inner peripheral side of the upstream portion of the pad surface has formed therein an oil groove having an opening in the inner peripheral side, an oil-supplying land is formed on an outer peripheral side of the upstream portion of the pad surface, and the oil-supplying land is connected to a connecting hole that guides lubricant from the outside.</p> |
