ABSTRACT:
A vane supporting apparatus for a hermetic compressor elastically supports vanes contacting to both cam faces of a dividing plate with thin torsion coil springs, and forms curved surface portions on upper ends of the vanes where the torsion coil springs are contacted, and thereby, height of the supporting apparatus supporting the respective vanes is reduced to miniaturize the compressor, and also, to prevent contacted portions between the vanes and the torsion coil springs from being worn away.
