Abstract
An enclosed motor compressor of a two cylinder type in which a clearance between the eccentric portion of the second rotary shaft and the second sub bearing is set greater than a clearance between the eccentric portion of the first rotary shaft and the first main bearing, and also there is formed a clearance between the eccentric portion of the second rotary shaft and the second main bearing, so that, even when the second rotary shaft moves in the axial direction thereof, there is eliminated the possibility that the eccentric portion of the second rotary shaft can be in touch with the second main bearing and second sub bearing in the axial direction, thereby being able to reduce noise. Also, the pair of main bearings further include, on the side of the compression elements, assembling jig mounting portions to which the assembling jig can be mounted. Due to this, when assembling the main bearings, the accuracy with which the main bearings are made parallel to each other can be improved, and thus the performance and reliability of the compressor can be improved, thereby being able to reduce noise.
