A hermetic compressor including a drive unit, a piston, a rotating shaft including an eccentric shaft portion and a weight balance portion located below the eccentric shaft portion, and an oil flow path having an upper oil hole formed in the rotating shaft and adapted to allow oil to be suctioned upward and dispersed to the upper side of the eccentric shaft portion and an auxiliary oil hole to allow a part of the oil being suctioned upward along the upper oil hole to be supplied into a gap between the eccentric shaft portion and the connecting rod. The eccentric shaft portion is installed with a plug member to close an upper end of the upper oil hole. The plug member is configured to selectively couple a weight balance member, which is separately fabricated from the rotating shaft, to an upper end of the eccentric shaft portion.
