摘要：
An oil supply passage (68) is formed inside a rotating shaft (56) of a compression mechanism (21). An oil supply passage (38) is formed inside a rotating shaft (36) of an expansion mechanism (22). A boss portion (81) is provided at a lower end of the rotating shaft (56). A shaft portion (82) that is engaged in the boss portion (81) is provided at an upper end of the rotating shaft (36). The circumference of a coupling part (80), which includes the boss portion (81) and the shaft portion (82) is covered by an upper bearing (42) of the expansion mechanism (22). The upper bearing (42) supports both the rotating shaft (36) and the rotating shaft (56).
