An abrasion preventing device for a hermetic reciprocating compressor. The device releases the impact generated between the slider and the shell of the compressor, thus to prevent possible abrasion of the contact part between the slider and the shell as well as abrasion of the piston. The device comprises a cylinder and a piston received and reciprocating in the cylinder, an end of the piston having a coupling projection. A shell, which is coupled to the piston, has a coupling projection. A bolt and nuts are used for coupling the piston to the shell by coupling the projections of both the piston and the shell to each other. A spring is provided on a coupling portion between the piston and the shell for absorbing the impact caused by striking of a slider on the shell during an operation of the compressor.
