Abstract: Disclosed herein is a thrust bearing for a turbo compressor, the thrust bearing has a structure that is modified in response to a portion where a deformation amount of a thrust runner is relatively large on the basis of magnitude of a force applied at the time of rotation of a shaft of a turbo compressor, to maintain a thickness of an oil film constantly and to increase a load supporting force of the thrust bearing, thereby ensuring improved durability of the thrust bearing.
