PURPOSE:To improve operation efficiency and life, and facilitate manufacture of a thrust support device which unautorotatably supports a revolving scroll member of a scroll compressor or the like. CONSTITUTION:An eccentric double row roller bearing 8 which prevents autorotation and supports a thrust load between a revolving scroll member 2 which performs eccentric rotation and a fixed member 8. At least three pair of roller bearings 8 are arranged around a rotational center O of the revolving scroll member 2. The paired roller bearings 8 are each formed by providing roller bearings 15, 16 which respectively support a thrust load on both side shaft parts of an eccentric shaft 14, being eccentric to each other. An angular boil bearing or a tapered roller bearing is used for the roller bearings 15, 16. |
