PURPOSE: An enclosed compressor is provided to improve performance by reducing the amount of discharged oil and inflow oil into a compression chamber as some oil is discharged to the side of a sealed container. CONSTITUTION: An enclosed compressor comprises a sealed container, a stator, a rotator, a crank shaft, a compression unit, a first fixing member, and a second fixing member. The compression unit is connected to the crank shaft to suck and compress refrigerant. The compression unit discharges the compressed refrigerant to the inside of a sealed container. The first fixing member is fixed to the sealed container, and supports a first bearing unit of a crank shaft from the rotator. The second fixing member is fixed to the sealed container, and supports a second bearing unit of the crank shaft from the rotator. The crank shaft comprises a first oil hole(711) penetrated in an axial direction, and one or more second oil holes. The second oil holes are penetrated through the outer surface of the crank shaft. One or more second oil holes are upwardly inclined. |
