PROBLEM TO BE SOLVED: To provide a scroll fluid machine, preventing an erection angle of a rotating lap from being unequal or preventing abnormal deformation caused by difference in cooling rate between each of parts after forging when a swirl end plate of a swirl scroll is manufactured by die-cast of aluminum-based metal so as to be as thin as possible, preventing, as far as possible, the swirl end plate from being locally bent or deformed caused by difference in generated heat or pressure receiving strength between each of parts during operation, and easily feeding oil to each pivot part. SOLUTION: A rear surface of the swirl end plate 4 has the pivot part of a following body 13 in each self-rotation prevention mechanism 12, and a reinforcement bearing plate 7 is detachably superposed on and tightly attached to the rear surface of the swirl end plate. An oil filler port 22 with respect to the following body 13 penetrates the reinforcement bearing plate 7. COPYRIGHT: (C)2007,JPO&INPIT
