Abstract

A turbocharger includes: a thrust bearing fixed to a turbocharger main body; and a supply oil passage provided in the turbocharger main body to the thrust bearing. The thrust bearing includes: an insertion hole in which to insert the turbine shaft; pressure receiving portions displaced from one another in phase in a rotational direction of the turbine shaft, and each configured to form an oil film between the pressure receiving portion and the thrust collar to receive a thrust load by use of oil film pressure; and intervening portions each located between two of the pressure receiving portions adjacent in the rotational direction of the turbine shaft, and being further away from the thrust collar than the pressure receiving portions. The intervening portion vertically under the insertion hole at least partially has a surface further away from the thrust collar than the other intervening portions.
