Abstract
In a thrust bearing for a turbocharger of the type having a thrust metal formed with a lubricating oil passage in communication with a lubricating oil feed port, a thrust bushing and an oil thrower, the inner peripheral wall of the thrust metal is formed with an annular oil reservoir and a single or plural small-diameter holes are axially extended through the wall of the thrust metal so as to intercommunicate between the oil reservoir and the outer peripheral wall of the thrust metal, that is, the thrust load carrying surface, whereby a sufficient quantity of lubricating oil can issue through such small-diameter holes to the load bearing surface. Because of this arrangement, the overall lubricating oil required may be reduced yet reliable and dependable operation can be ensured. In addition, the thrust load carrying capacity can be remarkably increased.
