PROBLEM TO BE SOLVED: To increase the arrangement number of rolling bodies according to load capacity by using a rolling body as a roller. SOLUTION: This bearing is an eccentric thrust bearing located between a revolving scroll member 3 and a compressor frame 5, and comprises first and second roller units 9 and 10 disposed on the inner surface of the revolving scroll member 3 and the compressor frame 5, respectively; and an intermediate race 11 disposed with it nipped therebetween. The roller units are provided with holders 12 and 14 and roller groups 13 and 15 held thereby, respectively. The roller units and the respective roller groups are aligned in a form to be approximately linearly rolled along respective azimuths of an x-axis and a y-axis on the revolving plane of the revolving scroll member 3. |
