Abstract: An electric compressor includes a housing including a compression part housing, a shaft support housing, and a motor housing fastened by a plurality of fastening members. A peripheral wall has a plurality of thick-walled portions that protrudes inwardly in a radial direction and through which their associated fastening members are inserted. The fixed scroll base plate has a plurality of protruded portions each protruding outwardly in the radial direction and disposed between the thick-walled portions in a circumferential direction. The fixed scroll base plate has a plurality of pillar portions each extending from the protruded portions toward the shaft support housing in the axial direction and spaced from each other in the circumferential direction. The elastic plate is held at a plurality of spots by the plurality of pillar portions and the shaft support housing.

Abstract: A scroll electric compressor includes a housing, a rotary shaft, an electric motor, a fixed scroll, an orbiting scroll, a compression chamber, a discharge chamber, and an oil storage chamber. The housing has a discharge housing including an end wall, a first peripheral wall, a stepped portion, and a second peripheral wall. The fixed scroll has a flange in contact with the second peripheral wall. The stepped portion, the second peripheral wall, the flange, the outer peripheral wall cooperate to define an annular space around the fixed scroll. The annular space is in communication with the discharge chamber or the oil storage chamber.
