Document Type and Number:
Japanese Patent JP2008025462

To provide a hermetic scroll compressor solving a defect that an edge part interferes with a chip seal groove wall surface when force acts on a chip seal in a twisting direction due to a rectangular chip seal section shape, floating performance is dropped, and refrigerant leaks into a compression chamber in a lower pressure side by crossing the chip seal to degrade performance.

In a scroll compressor, a rising property of the chip seal is improved by forming a section of the chip seal 244 in a shape having a chamfer shape relief part 286 in an anti-seal surface outer side in a roughly half winding section from a turning scroll 213 winding completion end 285 to a winding start side.
