Abstract

PURPOSE:To improve mass producibility, manufacturing accuracy and performance by piling up plural round slice shaped small pieces consisting of a curve formed by press working, etc., in the same phase to form a lap part and fixing them to panel plates. CONSTITUTION:Piling up one or more round slice shaped small pieces 5 using fixing pins 7 stood on the panel plates 3a, 4a of fixed scroll members 3 and turning scroll members 4 as guides, the round slice shaped small pieces 5 and the panel plates 3a, 4a are connected at prescribed positions by appropriate fixing means. As each of the small round slice shaped pieces 5 is combined to be in the same phase, they make as whole a shape similar to a scroll member cut out from one metal piece. By so doing, the machine can be manufactured at low costs by a highly accurate and highly productive method such as press blanking, etc., replacing usual milling machining methods.
