Abstract
There is provided a high performance compressor that causes no possibility of mixing foreign materials or of leaking refrigerant, that reduces strain otherwise generated in a compressor mechanism section and that is highly reliable even for a long-term use. The compressor mechanism section in which pairs of prepared holes are formed at a plurality of points on an outer peripheral face thereof is disposed within the closed container. Caulking punches are positioned to positions corresponding to those of the prepared holes and a region including the corresponding positions is heated. Then, when the punches are driven by pressing machines, portions of the container wall of the closed container plastically deform as the convex portions and enter the prepared holes. When the container wall cools down, the pair of convex portions of the container clamps a part between the prepared holes.
