Abstract (en)
A hermetic scroll compressor (1) includes a scroll compression mechanism (7) supported via a bearing member (6), a motor (8) connected to a drive shaft (11) supported with the bearing member (6), and a balance weight (34) provided on an end surface of a rotor (10) of the motor (8) along a periphery of the rotor (10), the end surface being on a side facing the bearing member (6). A length in an axial direction (L) of a journal bearing part (6A) pivotally supporting the drive shaft (11) in the bearing member (6) is set to 0.8 to 1.6 times a bearing diameter (D) and a flange part (34A) rising in the axial direction from a periphery region of the balance weight (34) is provided to overlap with a periphery side of an extended part in the axial direction (6B) of the journal bearing part (6A).
