摘要： A scroll compressor for reducing fluid leakage at step portions of scroll members and improving the compression efficiency is disclosed. The reduction of leakage and a high compression efficiency can be realized without increasing the precision in the manufacture of the members. Between the engaged scroll members, a high-pressure space is formed close to the spiral center, and among points at which the spiral walls contact with each other immediately before the innermost closed space communicates with the high-pressure space, the innermost point is defined as a base point. The angular distance from the base point to the outer end of the spiral, measured along the inner-peripheral face of the spiral wall, is approximately 4&pgr; rad. The angular distance from the base point to the step portion of each end plate, measured along the inner-peripheral face of the spiral wall, is equal to or more than approximately 3&pgr; rad.
