Abstract
A co-rotating scroll compressor includes a driving-side scroll member (), a driven-side scroll member (), a pin ring mechanism (), a driving-side bearing () that rotatably supports the driving-side scroll member (), and a driven-side bearing () that rotatably supports the driven-side scroll member (). A center of gravity of at least one of the driving shaft (), the driving-side scroll member (), and the driven-side scroll member () is shifted from rotation centers (CL, CL) by a predetermined distance. The predetermined distance is set so that a total bearing load obtained by centrifugal force and fluid compression that is 5% of a dynamic load rating of the driving-side bearing () and the driven-side bearing () or more is generated.
