Abstract
Provided are an inlet guide vane and a centrifugal compressor such that air can be caused to efficiently flow in with use of a simple shape. The inlet guide vane is disposed upstream of an impeller in a flow path of a centrifugal compressor. The inlet guide vane has: a plate-shaped plate section that is disposed in the flow path; and a rotation part that causes the plate section to rotate along an axis of rotation aligned with the radial direction of a rotary shaft of the centrifugal compressor. In a cross-section orthogonal to the axis of rotation of the rotation part, the plate section has, at the leading edge thereof on the upstream side of the flow path, a bent part that is tilted with respect to the other portions.
