<P>PROBLEM TO BE SOLVED: To provide a hermetic type compressor which uses one component for configuring sliding loss reduction and abrasion resistance improvement of a thrust section, and which has high efficiency and reliability and is low-cost. <P>SOLUTION: A thrust ring 121 is arranged to make contact with a collar part 112, is formed with a substantially semispherical part 123 over the entire circumference of the collar part 112 to make line-contact therewith, and is provided with a rotation restriction means 124 for restricting rotation with a thrust surface 122. As the collar part 112 and the substantially semispherical part 123 of the thrust ring 121 make contact only by line-contact, a sliding area can be reduced, making the highly efficient hermetic type compressor, and sliding reduction is formed by one component, resulting in low cost. <P>COPYRIGHT: (C)2012,JPO&INPIT |
