A high-performance and high-reliability scroll compressor which prevents seal property failure at seal necessary points, tooth tip contact, abnormal wear of an elastic body, fatigue failure, etc. A radially outward peripheral projection (4c) is formed on the full outer peripheral surface of a separation plate (4). The peripheral projection (4c) is set to an outer diameter reduced, relative to the inner diameter of the shell main body (9) before a shell lid (20) is sealed by welding, etc., by the dimension corresponding to the shrinkage amount of a shell main body (9). That is, before welding, a minute gap occurs between the outer peripheral surface of the peripheral projections (4c) and the inner peripheral surface of the shell main body (9). Then, the separation plate (4) is inserted into the shell main body (9) and further the separation plate (4) and a frame (3) are fixed. After this, when the shell main body (9) and the shell lid (20) are welded, because of shrinkage of the shell main body (9) after the welding, the outer peripheral surface of the peripheral projections (4c) of the separation plate (4) comes in tight contact with the inner peripheral surface of the shell main body (9), whereby the space is partitioned and sealed between a high pressure space (30) and a low pressure space (31).

[ What is claimed is:] [1.] A scroll compressor comprising:a sealed vessel including a shell main body and a shell lid sealingly attached to said shell main body to close a top face of said shell main body;a fixed scroll arranged within said sealed vessel so that motion of said fixed scroll in radial and rotation directions is restrained, said fixed scroll having a plate-like spiral tooth;an orbiting scroll having a plate-like spiral tooth and forming a compression space by combining said plate-like spiral teeth of said fixed scroll and orbiting scroll;a frame fixed to an inner peripheral surface of said shell main body and slidably supporting said orbiting scroll; anda separation plate arranged in tight contact with an inner peripheral surface of said sealed vessel without welding between said separation plate and said inner peripheral surface of said sealed vessel, and out of contact with end faces of both of said shell main body and said shell lid, so that a space in said sealed vessel is divided into a high pressure space and a low pressure space, wherein said frame is located within said low pressure space.
