Beschreibung
Zusammenfassung:	A compressor includes a compression mechanism, a drive shaft, a bearing, and an oil supply passage configured to supply lubrication oil to a clearance between the drive shaft and the bearing. The drive shaft includes a large-diameter shaft part supported by the bearing, and a small-diameter shaft part connected to a lower end part of the large-diameter shaft part. A sealing part is configured to reduced or prevent oil leakage from the bearing includes an oil receiving surface formed in the bearing housing so as to face a stepped surface formed at a boundary between the large-diameter shaft part and the small-diameter shaft part. A clearance is formed between the oil receiving surface and the stepped surface so as to surround an outer periphery of the small-diameter shaft part.
