PURPOSE: To provide a scroll type fluid machinery capable of control an increase in inclination vibration of Oldham's ring by simple adjustment. CONSTITUTION: In the fluid machinery wherein a fixed scroll and a rotary scroll are meshed with each other to rotate the rotary scroll while preventing it from autorotation by the Oldham's ring 18 provided between an end plate 6 of the rotary scroll and a frame 10, whereupon (s) is taken as the distance between the end plate 6 of the rotary scroll and the frame 10, and (t) is taken as the thickness of a ring section 19 of the Oldham's ring 18, the clearanceδobtained by (s-t) is set toδ/r<=0.01 to the radius (r) of the ring section 19 of the Oldham's ring 18. Inclination vibration of the Oldham's ring 18 is thus restricted from increasing by simply adjusting the thickness of the ring section 19 of the Oldham's ring 18.
