A scroll-type fluid machine in which: a fixed scroll and a moveable scroll are disposed in a housing; a fluid pocket, the volume of which varies, is formed between the fixed scroll and the moveable scroll; and a thrust plate for receiving the reaction force in the axial direction of pressure applied within the fluid pocket is disposed between the bottom plate of the moveable scroll and the housing. The scroll-type fluid machine is characterized in that at least the surface of the thrust plate facing the bottom plate of the moveable scroll is subjected to tin plating. As a consequence, it is possible to efficiently produce, at a low cost, a thrust bearing which is disposed between the bottom plate of the moveable scroll and the housing, exerts excellent seizure resistance, and has a high PV limit level and a low friction coefficient.
A scroll-type fluid machine in which a fixed scroll and a movable scroll to revolve around the fixed scroll as being prevented from rotating are provided to a housing, a fluid pocket having a variable volume is provided between the fixed scroll and the movable scroll, and a thrust plate to bear an axial reaction force of a pressure applied into the fluid pocket is provided between a bottom plate of the movable scroll and the housing, characterized in that at least a surface of the thrust plate facing the bottom plate of the movable scroll is plated with tin-based metal.
