Abstract
A hermetic compressor includes a thrust ball bearing () on the thrust face () of the main bearing (). The thrust ball bearing () includes balls () held in a holder (), an upper race () and a lower race () arranged respectively on and beneath the balls (), and an elastic support member () below the balls (). The hermetic compressor is prevented from causing a load to be applied unevenly to the balls (), thereby achieving high efficiency, low noise level, and high reliability.
