PROBLEM TO BE SOLVED: To simply and easily attach/detach a cylindrical bearing case of a revolving scroll to/from the revolving scroll together with a bearing to change them when needed. SOLUTION: In scroll fluid machinery, the revolving scroll 7 is constituted by vertically disposing a revolving lap 9 on an end plate 8 which is pivoted on an eccentric shaft part 13 integrated with a drive shaft 12 through the bearing 14. A fixed scroll 1 is constituted by vertically disposing a fixed lap 5 on a fixed end plate 4. The revolving lap 9 is engaged with the fixed lap 5 to form a closed chamber between the revolving lap 9 and the fixed lap 5, and a rotation prevention mechanism 16 is disposed to prevent rotation of the revolving scroll 7. The cylindrical bearing case 15 holding the bearing 14 on which the eccentric shaft 13 integrated with the drive shaft 12 is pivoted is installed to be detachable from the revolving scroll 7 or a rear face of the bearing plate 11 integrated with the revolving scroll.
