ABSTRACT:
A unitized structure of a main bearing and a cylinder of a rotary compressor is disclosed. The cylinder is formed integrally with and directly in the main bearing. Further, the inner circumferential corner of the cylinder is shaped in a round form, and the corresponding circumferential corner of the roller is shaped also in a round form. According to the present invention, the fastidious adjusting procedure required in assembling the conventional compressor and the drop of the effciency due to the variation of the clearance between the cylinder and the main bearing are all eliminated, thereby improving the productivity and the product quality.
