Abstract
A compressor has a compressor body and a motor integrated with one another, with the structure in which the sub-assembly of the motor portion and the compressor body assembled by positioning centers of the motor and compressor casings with positioning pins. When the deformation of a flange surface of the motor casing is large on a side of the compressor casing, positioning pin holes may have positional dimensions where the positioning is difficult, and the rigidity of the motor casing is increased to avoid change to the dimensional positions of the pin holes of the motor casing after the sub-assembly process. Fastening seats to fasten a motor stator by use of fastening members and ribs to reinforce the fastening seats are thus provided inside the motor casing to increase rigidity of the motor casing and inhibit deformation of the positional dimensions of the positional pin holes.
