摘要

An inlet guide vane includes vane main bodies (42) having a pressure surface (S1) and a suction surface (S2) which extend along a radial-direction axial line (Ar). Each of the pressure surface (S1) and the suction surface (S2) has a blade-shaped surface along a surface of an imaginary blade shape (Pv) having a blade-like cross-sectional shape. At least one of the pressure surface (S1) and the suction surface (S2) has a thin portion-forming surface (St) which recedes toward an inside of the imaginary blade shape (Pv) more than the surface of the imaginary blade shape (Pv).
