Beschreibung
Zusammenfassung:	A sealed compressor comprises a sealed container (101) which accommodates an electric component (105) and a compression component (106); wherein the compression component (106) includes a shaft (110) including a main shaft section (111) and an eccentric shaft section (112), a cylinder block (114), a piston (126), and a main bearing unit (120) mounted to the cylinder block (114) and supporting the main shaft section (112) such that the main shaft section (112) is rotatable, a thrust ball bearing (132) mounted to a thrust surface (130) of the main bearing unit (120); and the thrust ball bearing (132) includes a plurality of balls(134) held in a cage (133), an upper race (135) having main surfaces one of which is in contact with upper portions of the balls (134); and a lower race (136) having main surfaces one of which is in contact with lower portions of the balls (134) and; a restricting means for restricting a displacement of the upper race (135) with respect to the shaft (110).
