Hermetic compressor

A hermetic compressor, comprising:

• a shell;
• a compressor body spaced apart from an inner surface of the shell, the compressor body including a motor and a compression unit configured to compress a fluid via a driving force of the motor, wherein the compression unit includes a cylinder block and a piston;
• a plurality of springs provided between the shell and the compressor body to elastically support the compressor body with respect to the shell;
• a plurality of first caps fixed to the inner surface of the shell;
• and
• a plurality of second caps fixed to the compressor body, the plurality of first and second caps being configured to support first and second ends, respectively, of each of the plurality of springs, wherein each of the plurality of springs is inclined with respect to an axial direction of the compressor body, wherein each of the first caps has a first spring base fixed to the inner surface of the shell to support the first end of one of the plurality of springs, each of the second caps has a second spring base fixed to the compressor body to support the second end of the one of the plurality of springs, each of the first spring bases has a first inclined surface configured to contact the first end of the one of the plurality of springs, and each of the second spring bases has a second inclined surface configured to contact the second end of the one of the plurality of springs, wherein each of the first spring bases is supported by the inner surface of the shell in the axial direction of the compressor body, and each of the second spring bases is supported by the compressor body in the axial direction of the compressor body, wherein the first and second inclined surfaces are inclined with respect to a longitudinal direction of the each of the first spring bases and second spring bases, and
• wherein:
• each of the first caps is provided with at least one first protrusion formed on a first fixing surface which is opposite to the first inclined surface;
• and the inner surface of the shell includes a plurality of grooves, each groove configured to receive one first protrusion.
