Abstract

PURPOSE:To form a missing part easily and correctly to reduce the cost of processing, by forming this circular missing part for weight balancing, along the outer circumferential edge of a spiral body on an end plate, from the spiral end side to the spiral beginning side, of the spiral body. CONSTITUTION:A movable scroll 4 of a scroll type fluid machine, is equipped with a disc-shaped end plate 4a and a spiral body 4b projected on the flat surface of the end plate 4a, and is driven as revolving against a fixed scroll 3. A circular missing part 4d for weight balancing, is formed along the edge of the end plate 4a on the outside of the spiral body 4b, from the spiral end side to the spiral beginning side, of this spiral body 4b. In this way, as the missing part 4d can be formed easily and correctly through such as a lathe turning processing, the cost of the processing can be reduced.
