た。(C) Problems to be solved by the invention However, in the conventional rotary compressor of this kind, when connecting the cylinder and the suction pipe, an impact force is applied to the collar until the suction pipe is slightly plastically deformed. The connection was made by pressing. As described above, in the rotary compressor in which the suction pipe and the cylinder are connected, the cylinder may be distorted or the connection position between the cylinder and the suction pipe may be displaced.

ラーである。(1) is a container which internally holds a rotary compression element (2) and an electric element (3) for driving the rotary compression element,
(4) is a cylinder, (5) is a bush made of a soft metal such as copper or aluminum, and (6) is press-fitted into the cylinder (4) through an opening (7) formed in the side wall of the container (1). The suction pipe, (8), is a collar that is press-fitted in the overlapping portion of the suction pipe (6) and the cylinder (4).
本考案の構成は以上であり、以下、第１図に示す吸込管
の接続部分の組立てについて説明する。The construction of the present invention is as described above. Hereinafter, the assembling of the connecting portion of the suction pipe shown in FIG. 1 will be described.

使用による衝撃力にて圧挿する。First of all, the bush (5) is inserted in the suction hole of the cylinder (4).
Is inserted through the opening (7). Next, the suction pipe (6) is press-fitted into the suction hole. Finally, the collar (8) is pressed into the overlapping portion of the cylinder (4) and the suction pipe (5) with an impact force by using a hammer or the like.

和する。At the time of press-fitting the collar (8), the bush (5) receives a large pressure between the cylinder (4) and the suction pipe (6) and rolls. By rolling the bush (5), the cylinder (4) and the suction pipe (6) are sealed, and the impact force applied from the collar (8) to the cylinder (4) is mitigated.

ることができる。(G) Effect of the Invention In the compressor of the present invention, since the bush is rolled between the cylinder and the suction pipe at the time of assembly, the impact force applied to the cylinder can be relieved by this rolling. Therefore, the distortion of the cylinder, which tends to occur during assembly, and the displacement of the connection position between the cylinder and the suction pipe can be suppressed as much as possible.
