Summary:To increase usefulness and simultaneously improve efficiency by improving the warm-up and start performance of an axial flow fluid machine. A radial gap (36) formed between a blade tip edge (35) and a guide surface (33) positioned facing the tip edge (35) is adjusted by supplying a cooling material (51) to guide wheels (21, 23) forming the guide surface (33) to cool the guide wheel (21, 23). Consequently, the start characteristics can be improved.
