The present invention relates to a mounting structure of a piston pin for a hermetic compressor. In the present invention, caulking portions (26) are beforehand formed in a connecting chamber (22) of the piston (20), and then, a piston pin (30) is fastened to the piston (20) by means of plastic deformation of the caulking portions (26). At this time, the caulking portions (26) are formed at upper and lower ends of an interference preventive portion (24) defined within the connecting chamber (22) and cause the upper and lower ends of the piston pin (30) to be fastened to the piston (20) within the connecting chamber (22) of the piston. According to the present invention, there is an advantage in that an outer diameter of the piston (20) is not changed during its assembling process, since the piston pin (30) can be fastened to the piston (20) merely by causing only the caulking portions (26) of the piston (20) to be subjected to the plastic deformation. |
