った。In the case of a conventional rotary compressor, for example, a two-cylinder source rotary compressor, a partition plate is interposed between two rotary compression elements, and the two rotary compression elements are sandwiched by a frame body having bearings on both sides. Since the rotation angles of the elements are shifted by 180°, the distances of the bearings from both rotating pressure line elements are different, and the compression force of the upper rotational compression element is applied to the upper bearing, while the compression force of the lower rotational compression element is applied to the upper bearing. The compressive force is applied to the lower bearing part, and stress is also applied to the bearing part, so there is a problem that the bearing part wears out.

A partition plate interposed between the rotary compression element is formed of two divided plates, and a journal hole is provided spanning both side plates to form an intermediate bearing portion of the rotating shaft, and a #-marked partition plate is provided. The invention is characterized in that the suction passage provided in the partition plate is formed at a position perpendicular to the dividing direction of the two dividing plates.

ル孔がズレるのを防鳥するものである。In this configuration, cf) the partition plate interposed between the rotary compression elements is used as an intermediate bearing, and the distances of the bearings located on both sides from each rotational pressure iMI are equalized, so that stress is applied to one side. In order to prevent the bearing part from being worn out and to form a suction passage in the partition plate in a step 9 perpendicular to the direction in which the partition plate is divided, the two pieces are divided when driving a collar to connect the suction pipe to the suction passage. This is to prevent birds from shifting the journal hole formed across the board.
