Abstract: A scroll-type compressor comprising mutually mating stationary and movable scrolls for forming a compression chamber. The shell of the compressor comprises a center housing, a front housing, and a rear housing. The stationary scroll is integrally formed with the center housing. The movable scroll is carried by an eccentric shaft portion of a drive shaft which is rotatably supported by the front housing so that the movable scroll can move in an orbit. The rear housing has a first set of bolt holes, and the front housing has a first set of threaded holes for receiving a first set of through bolts which are inserted in the first set of bolt holes from the rear side whereby the center housing is fastened between the front and rear housings by the fastening force of the through bolts.
