A crank shaft and manufacturing method of a hermetic compressor is provided to easily manufacture and to reduce the processing work by using a pipe-shaped shaft unit. A crank shaft and manufacturing method of a hermetic compressor comprises a shaft unit(30), an eccentric pin(43), and a pin unit(40). The shaft unit is formed with the processed pipe, and bored at inner of the shaft unit to form an oil passage. The eccentric pin is installed at the upper part of the shaft unit to transfer the power by integrally formed at the pin-body with a pin-body which is inserted to the shaft unit and fixed. The pin unit is bored at the pin-body and the eccentric pin to form the oil passage. |
