PURPOSE:To facilitate separation of waste from gas by forming a gas bleeder hole, which is to put oil supply hole formed in a rotary shaft in a single piece with a crank shaft stretching in the longitudinal direction of the compressing mechanism in communication with a sealed vessel in such an arrangement that its backmost part is inclined lower, and forming this backmost part to be used as a waster storage hole. CONSTITUTION:In this sealed compressor, a crank shaft 8 is rotated by a motor part through a rotary shaft 8a to which the rotor of said motor part is fixed, and a piston 7 of the compressor part is reciprocated through a connecting rod 9, to compress the refrigerant and discharge. At this time, the refrigerator oil 14 is sucked through an oil lead-in hole 16 formed at the bottom of said rotary shaft 8a, and supplied to parts to be lubricated via an oil supply hole 17 formed inclined. Here a gas bleeder hole 18 to put the oil supply hole 17 in communication to inside the sealed vessel is formed in the rotary shaft 8a in such a way that the backmost portion is inclined lower, and this backmost portion is made deeper than the oil supply hole 17 so as to be used as a waste storage hole 19, which shall serve separation and removal of waste from the gas.
