摘要:
A hermetic compressor of the present invention includes a thrust-ball bearing having balls (168) disposed in a holder (170) in a manner that the balls (168) roll along at least two tracks (182a, 182b, 184a and 184b). The invented structure decreases the number of balls (168) that roll along each of the tracks (182a, 182b, 184a and 184b), and reduces a frequency of sliding between the balls (168) and the tracks (182a, 182b, 184a and 184b), thereby alleviating wear of the tracks.
