Summary:PROBLEM TO BE SOLVED: To improve performance of an impeller.SOLUTION: An impeller includes a disc rotating around an axial line, and a plurality of blades 23 provided in the disc at intervals in a circumferential direction with the axial line as a center. A thickness of the blade 23 gradually decreases from the disc side toward a chip side, and a thickness reduction rate gradually decreases from the disc side toward the chip side.SELECTED DRAWING: Figure 4 【課題】インペラの性能向上を図る。【解決手段】インペラは、軸線を中心として回転するディスクと、軸線を中心とする周方向に間隔をあけてディスクに複数設けられているブレード２３と、を備える。ブレード２３の厚さは、ディスク側からチップ側に向かうに連れて次第に減少し、厚さの減少率がディスク側からチップ側に向かうに連れて次第に減少する。【選択図】図４
