Abstract
In a scroll compressor, a suction port has an inlet portion in which a cross-sectional area of a flow passage therein decreases, and an outlet portion in which a cross-sectional area of the flow passage therein increases. A main frame has a first surface in which the upstream-side opening of the suction port is formed, and which is perpendicular to the rotation shaft, and a second surface opposite to the first surface. A boundary part between the inlet and outlet portions is closer to the second surface than an intermediate line between the first and second surfaces in an axial direction. A wall surface of the outlet portion that is located on an inner side in a radial direction perpendicular to the axial direction is an inclined surface that is inclined inwardly in the radial direction, in a direction from an upstream side toward a downstream side.
