Abstract
A thrust bearing includes: a thrust plate in a disc shape having an outer diameter and an inner diameter formed by perforating a central portion of the thrust plate; a plurality of bump foils disposed radially on a top surface of the thrust plate; a plurality of top foils in a panel shape covering each of the bump foils, where bottom surfaces of the top foils are in contact with upper ends of the bump foils; and metal blocks radially disposed on the top surface of the thrust plate and formed to be spaced apart from the bump foils. The thrust bearing can be included in an air compressor of a vehicle.
