PROBLEM TO BE SOLVED: To provide a thrust bearing structure and a turbocharger appropriately supplying lubricant even if a thrust collar rotates at high speed.SOLUTION: This thrust bearing structure 32 includes the thrust collar 35 retained by a shaft 11 and rotating together with the shaft 11, and a pair of thrust bearings 36, 37 disposed at both sides of the thrust collar 35 in an axial direction. One side of the thrust collar 35 and the thrust bearings 36, 37 includes groove parts 36d, 37c provided at an outer edge part side of opposite surfaces 36c, 37c opposing to another side and extending in a direction around an axis. Another side of the thrust collar 35 and the thrust bearings 36, 37 includes projections 35d, 35e projecting toward one side, inserted in the groove part 36d 37c, and extending in the direction around the axis. |
