【００１２】この実施の形態において、前記図４に示す
密閉型回転圧縮機を製造するにあたり、ケース１の下端
開口部を底板２で気密的に閉塞して台座５上に固着する
のであるが、これを以下のようにして行っている。In manufacturing the hermetic rotary compressor shown in FIG. 4 in this embodiment, the lower end opening of the case 1 is hermetically closed by the bottom plate 2 and fixed on the pedestal 5. This is done as follows.

On the other hand, inside the pedestal 5, the case 1
The opening 5b having an inner diameter smaller than the outer diameter of the bottom plate 2 and larger than the outer diameter of the bottom plate 2 is provided.

この時、言うまでもなく底板２はケース１の下端開口部
内に嵌合されている。In this state, the case 1 integrated with the bottom plate 2 is inserted from above the pedestal 5 into the opening 5b of the pedestal 5 so that the lower end face of the case 1 contacts the upper surface of the pedestal 5. , The case 1 is integrally set on the base 5.
At this time, needless to say, the bottom plate 2 is fitted in the lower end opening of the case 1.

を容易に行うことができる。Here, in this embodiment, as shown in FIG. 3, the pedestal 5 is provided with a concave portion 5c having a shape along the outer diameter of the case 1 and holding the case 1 from the outside. The opening 5b is provided in the recess 5c. With this configuration, when the case 1 is integrally set on the pedestal 5, the case 1 is dropped into the recess 5c for positioning. By sandwiching, this setting can be easily performed.

面側で外部に露出する。With this arrangement, the opening 5b of the pedestal 5 is formed.
Since its inner diameter is larger than the outer diameter of the bottom plate 2, referring to FIG. 3, the peripheral wall surface of the opening 5b of the pedestal 5 and the outer peripheral surface of the bottom plate 2 face each other with a constant gap therebetween. Thus, a part of the lower end surface of the case 1 is exposed to the outside on the back surface side of the bottom plate 2 over the entire circumference thereof.
