PURPOSE: A closed container structure is provided to improve reliability of compressor by minimizing noise radiation from the closed container, and improve efficiency of compressor by effectively radiating the heat generated from an interior of the closed container. CONSTITUTION: A closed container(20) of a hermetic compressor has a motor part for generating a driving force and a compressor part for compressing a gas by the driving force transmitted from the motor part. The close container has an inner wall having a protrusion(23) formed all over the inner wall. The pulsating pressure wave generated from the interior of the closed container is attenuated by the protrusion formed at the inner wall of the close container.
