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 null1-null1null and null2-null2null respectively, and a stepped portion formed along a curve null1null-null2null 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 compressor assembled under desirable working conditions at a low cost is disclosed. In the compressor, the first rolling bearing for permitting axial movement of the shaft is inserted into the first housing from the side where the compression mechanism is to be provided, and the second rolling bearing for restricting axial movement of the shaft is inserted into the first housing from the other side where the driving source is to be provided. The shaft is inserted into the first housing from the side where the compression mechanism is to be provided. A seal member is further provided between the rolling bearings for sealing an area between the insertion hole and the shaft, wherein the seal member is inserted into the insertion hole of the first housing from the side where the compression mechanism is to be provided before the shaft is inserted into the insertion hole.
