Abstract
A centrifugal compressor includes: an impeller; an inlet pipe portion forming an intake passage to introduce air to the impeller; and a throttle mechanism capable of reducing a flow passage area of the intake passage upstream of the impeller. The throttle mechanism includes an annular portion configured to move between a first position and a second position upstream of the first position in an axial direction of the impeller, and a strut supporting the annular portion. The strut extends toward at least one of an outer side in a radial direction of the impeller or a downstream side in the axial direction of the impeller with an increase in distance from the annular portion.
