Scroll compressor

摘要

A scroll compressor (1) prevents the rotation of an orbiting scroll (7) and reduces manufacturing cost. This scroll compressor has a housing (3), a fixed scroll (5) having a first end plate (5a) and a first spiral wall body, an orbiting scroll (7) having a second end plate (7a) and a second spiral wall body, rotation-preventing portions (11) provided for at least one of the housing and the orbiting scroll, which allow the orbiting scroll to revolve while preventing the rotation thereof, a wall body shoulder portion formed along an upper edge of the second spiral wall body, and a step portion formed on the first end plate. In this scroll compressor, the shoulder portion and the step portion contact with and slide along each other, and a phase at which the shoulder portion is disposed to the center of the orbiting scroll is different from phases at which the rotation-preventing portions are disposed.
