PURPOSE:To reduce extent of load acting on a sliding part, by forming a key or the sliding part between a turning scroll and a block of an Oldman's ring with an irony metal as well as forming other parts with a compound material using an aluminum alloy. CONSTITUTION:A scroll compressor is made up of a key 18a of an Oldman's ring 18 to be slidden with a turning scroll and a block and a ring 18b. In this case, the key 18a of the Oldman's ring 18 is made up of an irony metal, and the ring 18b not having a sliding spot is made up of a compound material using an aluminum alloy. With this constitution, at the time of operation of the scroll compressor, load acting on the key 18a or the sliding part is reducible as compared with the case where the Oldman's ring 18 is of the irony metal alone. In addition, in combination of the fact that the key 18a is made up of a wear resisting irony metal, wear and abrasion resistance is improvable and, what is more, wear and seizure or binding or the like are eliminable. |
