Abstract
A diameter of a main bearing memberis defined as Dm, a length thereof is defined as Lm, a diameter of the eccentric bearing memberis defined as De and a length thereof is defined as Le. A ratio (=Lm/Dm) of the length and the diameter of the main bearing memberand a ratio (=Le/De) of the length and the diameter of the eccentric bearing memberare set to Le/De≦Lm/Dm≦1. Therefore, contact at edge portions of both ends of the eccentric bearing memberdoes not occur, and it is possible to prevent contact at edge portions of both ends of the main bearing membereven if the main shaftinclines, and to reduce a viscosity loss caused by oil. Hence, the present invention provides a scroll compressor securing reliability of the bearing membersandand having high efficiency.
