Abstract
In a scroll type machine, such as a scroll compressor, the difference in level between the axial end surface of a wear-resistant plate (40) installed at the periphery of the end plate (17) of an orbiting scroll (16) and the axial end surface of the end plate (17) is set within 0.+-.10 .mu.m. This difference in level (.delta.) is set to this range to prevent wear of the wear-resistant plate and the end plate of the orbiting scroll and to prevent deterioration in the performance of the scroll-type compressor so that a scroll-type compressor with high performance and high reliability can be realized.
