In an abrasion preventive structure of a reciprocating compressor, by forming a coating layer made of Ni-P alloy material having high hardness onto the surface of a frame at which front ( 92 ) and rear ( 93 ) resonance springs are contacted or spring mounting grooves ( 91 a, 92 a) of a spring supporting rod ( 91 ) or spring fixation protrusions or the inner circumference of a cylinder built-in type frame, although each resonance spring ( 92, 93 ) is rotated while repeating compression/relaxation, it is possible to prevent abrasion of the spring mounting grooves ( 91 a, 92 a) or the spring fixation protrusions, and accordingly reliability of the compressor can be improved.
