Each of the spoke portions connects an inner circumferential wall surface of the air introduction hole and the annular portion. The casing treatment includes a tubular portion provided on an upstream side of the annular portion in the air introduction hole in an introduction direction of the air, and wing-like portions. Each of the wing-like portions extends from the tubular portion toward a downstream side in the introduction direction of the air.
