The piping (40) has a boss (36) fitted into a through hole (4a) from outside of a hermetic container (4) and forming a joint (42) in cooperation with the hermetic container (4) to seal up the through hole (4a), an internal pipe (38) inserted through the boss (36) into a scroll unit (12) and made of a copper-plated, iron-based material, and an external pipe (8) inserted into the internal pipe (38) and projecting from the boss (36) to the outside of the hermetic container (4). The external pipe (8) is made of a copper-based material. The boss (36) is made of a copper-plated, iron-based material and has an iron-exposed region (48) where the iron-based material is exposed and where the joint (42) is formed. |
