PROBLEM TO BE SOLVED: To provide scroll fluid machinery, for improving durability of a rotation prevention mechanism of a movable scroll and productivity. SOLUTION: The rotation prevention mechanism 10 has: a constraint member 11 interposed between a drive casing and a movable scroll to constrain rotation of the movable scroll; a fixed side pin projecting in the drive casing and engaged with the constraint member; a turning side pin projecting in the movable scroll and engaged with the constraint member, and turning around an axial center of the fixed side pin while constrained by the constraint member; a means for reducing influence of sliding between the constraint member and the fixed side pin and between the constraint member and the turning side pin.
