<P>PROBLEM TO BE SOLVED: To provide a centrifugal compressor that makes a guide vane suitably appear in a diffuser channel and prevents the compression efficiency from decreasing, and also to provide a method for assembling the guide vane. <P>SOLUTION: A compressor includes: a wall plate 51 having a plurality of slits 51a; a plurality of vanes 52 appearing in the diffuser channel through the slit 51a and having a shaft 52a; a collar-shaped diffuser plate 53 disposed on the shaft 52a at a position abutting against a base end of the vane 52; a diaphragm 54 and a retainer 55 assembled to the shaft 52a; and a spring 56 biasing the vane 52 to the diffuser channel side. The diffuser plate 53 is prepared one by one per the vane 52. As a result, a clearance around the vane 52 is set to be small. <P>COPYRIGHT: (C)2012,JPO&INPIT |
