PROBLEM TO BE SOLVED: To provide a scroll compressor in which lubricating oil supplied to each of bearings is prevented from flowing out to the outside of a casing, together with refrigerant, to thereby reduce an amount of oil discharge.SOLUTION: A main shaft part (14) of a drive shaft (11) is rotatably supported by an upper main bearing (36) and a lower main bearing (37). An eccentric shaft part (15) of the drive shaft (11) is engaged with a pin bearing (35) of a movable scroll (70). An oil supply passage (16) and an oil discharge passage (17) are formed in the drive shaft (11). Lubricating oil drawn up from an oil reservoir part (21) circulates in the oil supply passage (16) and is supplied to the pin bearing (35) and the upper main bearing (36). The lubricating oil after supplied to the pin bearing (35) and the upper main bearing (36) circulates in the oil discharge passage (17) and is then discharged to an oil discharge space (28) disposed below the lower main bearing (37). |
