    摘要： In a compressor (1) in which a compression mechanism (10,14) incorporated in a housing is driven by a drive shaft (7) penetrating the housing, and the compression mechanism is lubricated by mist-form lubricating oil contained in a low-pressure gas refrigerant sucked into the housing, the lubricating oil in a space (38) is prevented from entering a bearing (8) and deteriorating grease in the bearing. An equalizing hole (40) is formed to allow the space to communicate with the atmosphere, the space being defined between the bearing (8) pivotally supporting the outer end of the drive shaft on the housing and a shaft seal (35) disposed on the inside of the bearing to seal a gap between the drive shaft and the housing.
