Abstract
A diameter of a main bearing member 12m is defined as Dm, a length thereof is defined as Lm, a diameter of the eccentric bearing member 11e is 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 member 12m and a ratio (=Le/De) of the length and the diameter of the eccentric bearing member 11e are set to Le/De≦Lm/Dm≦1. Therefore, contact at edge portions of both ends of the eccentric bearing member 11e does not occur, and it is possible to prevent contact at edge portions of both ends of the main bearing member 12m even if the main shaft 13m inclines, and to reduce a viscosity loss caused by oil 9a. Hence, the present invention provides a scroll compressor securing reliability of the bearing members 12m, 11e and 16s and having high efficiency.
