A mounting structure for a piston pin of a hermetic compressor is provided. A connecting chamber formed at an end of the piston allows the piston to be connected to a crankshaft via a connecting rod. Caulking portions provided at upper and lower ends of the connecting chamber receive and hold the piston pin, thus engaging the piston, piston pin, connecting rod, and crankshaft. An interference preventive portion formed adjacent the connecting chamber prevents interference between the piston and the connecting rod when the components are so engaged. Because a separate structure within the piston receives and holds the piston pin, an outer diameter and/or cross section of the piston is not altered during the assembly process, thus improving system reliability and performance. |
