。 A return vane that is placed in a continuous return flow path from a diffuser such as a multistage centrifugal compressor, and that forms a blade inlet by arranging at least one divided block in series, and each block is slightly different. In order to form a blade inlet angle and move each block stepwise into the return flow path or into the space surrounded by the diaphragm constituting the return flow path, the actuator housed in the space and each block are aligned along the axis. A retractable return vane at the blade inlet connected via a rod that can be expanded and contracted in both directions.
