Abstract

A compressor for receiving at least one compression element in a sealed container is provided. The sealed container comprises a container body and a cover member for blocking an opening of the container body, both of which are made of an aluminum material. The cover member is electrically welded to the container body over an entire circumference of the cover member, and thick ribs with a thickness dimension extending from a circumference portion to a central portion are formed with a predetermined pitch on the cover member. In this manner, an increase in the manufacturing cost and a reduction of the workability can be substantially suppressed, while the reliability of the sealed container of the compressor and the aluminum members assembled by arc welding can be substantially improved.
