Abstract

An embodiment includes: a cylindrical motor case surrounding a compression mechanism about an axis; a lower case closing an opening of the motor case, fitted to an inner circumferential face of the motor case, and defining an accommodation chamber between the motor case and the lower case where a refrigerant is introduced; a first O-ring provided about the axis at a facing portion where the motor case and the lower case fitted to each other face each other in a plane; and a second O-ring provided about the axis in the facing portion, the first O-ring is provided at a position closer to a starting point on the accommodation chamber side of the facing portion than the second O-ring, the first O-ring has better refrigerant resistance and/or oil resistance than the second O-ring, and the second O-ring has better sealing performance than the first O-ring at a temperature of −20° C. or lower.
