There is provided a scroll-type compressor in which a scroll-type compressing mechanism comprising a fixed scroll and an orbiting scroll, a motor, and a frame to which a main bearing is mounted to rotatably support a motor rotating shaft for driving the orbiting scroll are disposed in an enclosed housing composed of a plurality of housing members fastened by bolts, and the interior of the enclosed housing is divided into a high-pressure chamber and a low-pressure chamber by an end plate of the fixed scroll. The fixed scroll is fastened to the frame by making a plurality of holes passing through the frame in the frame, by inserting bolts into the holes from the side of the low-pressure chamber, and by screwing the bolts into the fixed scroll. Thereby, an adverse effect of thermal deformation or pressure deformation of the enclosed housing on a scroll-type compressing mechanism can be averted.
