<P>PROBLEM TO BE SOLVED: To provide a hermetically-sealed compressor improved in performance and reliability by suppressing lowering of rigidity of a cylinder block and arranging members having an aligning function. Ž<P>SOLUTION: An outer connection section and an inner connection section allow displacement around each axis relative to an inclination of a shaft 121 due to a compression load or the like, so that an inclination of an inner-periphery member is permitted, a clearance formed by an outer-periphery member and a lower race 193 remains constant, and a load can be uniformly imparted to a ball 191 of a rolling bearing 190. Therefore, abrasion of a race due to a bias of a load and lowering of a service life of a rolling bearing due to an idling operation of steel balls can be prevented to improve reliability. Further, vibration generated during transportation or the like does not transmit an excessive load to the rolling bearing 190 because a support member 195 is elastically deformable in the direction of a thrust of the shaft 121. With this effect, breakage of a race can be prevented and reliability is improved. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
