In the fluid displacement device, the first and second annular races are formed with radially recessed portions at their outer periphery and radius the moving scroll 26 and the housing, respectively, using the moving scroll and the caulking component of the housing. Fixed to the recessed portion in the direction, fastening the fixed scroll 25 to the housing 10, connected to the fixed scroll so that the kinetic scroll cooperates with the fixed scroll to form a fluid pocket therebetween and relative to the fixed scroll. Rotation is prevented, and when the movement scroll is driven to orbital movement without rotation, the fluid pocket is displaced between the movement scroll and the fixed scroll.
