<P>PROBLEM TO BE SOLVED: To provide a twin rotary scroll type compressor in which both scrolls can be restrained from being inclined while bringing a drive side spiral wall into pressure-contact with a driven side spiral wall in the pressure-contact direction. <P>SOLUTION: A driven side preload imparting member 40 which is used for imparting a load in such a direction that the drive side spiral wall 31b is brought into pressure-contact with the driven side spiral wall 32c, is arranged at the driven side bearing 18 of the twin rotary scroll type compressor 11. The driven side preload imparting member 40 is disposed, in the driven side outer ring 18b of the driven side bearing 18, at a position which is closer to a compression chamber 33 from the center in the axial direction thereof. A drive side preload imparting member 41 which is used for imparting a load in such a direction that the drive side spiral wall 31b is brought into pressure-contact with the driven side spiral wall 32c, is arranged at a drive side bearing 16. The drive side preload imparting member 41 is disposed, in the drive side outer ring 16b of the drive side bearing 16, at a position which is closer to the compression chamber 33 from the center in the axial direction thereof. <P>COPYRIGHT: (C)2013,JPO&INPIT |
