Abstract (en)

A compressor is provided as a compact unit while effectively preventing coolant leakage and assuring safety by optimizing the contact pressure at a seal member held between a plurality of housing members so as to minimize the size or the number of fasting members. In the compressor comprising at least two housing members, in which the compression mechanism is housed, a seal member (13, 14, 15) held between the housing members and fastening members used to fasten the housing members and the seal member as one. The seal member (13, 14, 15) has a bead portion (55, 56, 57) formed to assume a plateau shape.
