Abstract
A sliding-vane rotary compressor including a drive shaft having one end portion rotatably supported by a bearing fitted in a central hole in a rear block, the opposite end portion of the drive shaft extending loosely through a central hole in a front block and being rotatably supported by a bearing fitted in a central bore in a front head, the front head having a plurality of support ribs held in abutment with an outside end face of the front block for supporting the front block. With this construction, the front block and the front bearing are thermally separated from one another, so that a bearing clearance between the front head and the drive shaft is kept always constant even when the front side block is subjected to a high temperature. In addition, by the use of the support ribs, a thinner side block can be used.
