PROBLEM TO BE SOLVED: To provide a thrust bearing structure in a turbocharger, capable of increasing a thrust withstand load without increasing slide resistance. SOLUTION: An oil groove 34 is provided on an inner peripheral face 27a of a through-hole 27 of a thrust plate 21, and is communicated with a space between the thrust plate 21 and a flange part 25 in a turbine side of a thrust bush 22. In addition, the oil groove 34 is communicated with a space between the thrust plate 21 and a flange part 26 in a compressor side of the thrust bush 22 via a throttle 34a. Lubricating oil is supplied from the oil groove 34 to the space between the thrust plate 21 and the flange part 25 in the turbine side of the thrust bush 22. A small amount of lubricating oil throttled by the throttle 34a is supplied to the space between the thrust plate 21 and the flange part 26 in the compressor side of the thrust bush 22.
