摘要： A scroll compressor comprises a fixed scroll member and a revolving scroll member that engage with each other with their centrifugal walls, wherein the revolving scroll member is supported to revolve with respect to the fixed scroll member, but to avoid self-rotation thereof. The spiral-starting portion of the centrifugal wall comprises non-stepped portions formed along curves of &bgr;1-&bgr;1′ and &bgr;2-&bgr;2′ respectively, and a stepped portion formed along a curve &bgr;1′-&bgr;2′ that provides a thickness increase area encompassed by its upper-side curved surface and its lower-side curved surface. The discharge port is located on the end board of the fixed scroll member to partly overlap with the thickness increase area by partly hollowing the lower side of the stepped portion with the prescribed height.

摘要： A mechanism preventing rotation is mainly composed of plural swivel pins (31) projectingly provided on an end plate of a swiveling scroll (15), housing pins (32) which is the same number as the swivel pins (31) on a front end plate (11b) provided onto the end plate, and a pin engaging member (33) having plural holes (34) in which these pins (31) and (32) respectively. These holes (34) are formed sufficiently larger diameter than the swivel pin (31) and the housing pin (32). According to this mechanism preventing rotation, while the swiveling scroll (15) performs a revolution swivel movement, these pins (31) and (32) and the inner surface of the pin engaging member (33) controls radial maximum variation with sliding-contacting each other. Accordingly, fluid leak that occurs by an engaging position error of a stationary scroll and the swiveling scroll is effectively prevented and long service life and improvement of degree of freedom of designs are actualized.
